Need advice. Does my straight best friend have feelings for me?

Okay, so I just wrote half a novel on here, then accidentally erased everything, so I'm just gonna try to make this as short as possible. I need advice. I'm so madly in love with my best friend, it hurts me. I've been best friends with Joe since the eighth grade. We always made the dumbest jokes together and spent as much time together as we could. I realized I was gay when I was 18. I came out to him and most of my friends when I was 21. Joe said he was fine with it, and always suspected it. We carried on like nothing ever changed. But I have never told him how much I love him. For the longest time, I always thought he was straight. He's had many girlfriends and always talks about how sexy random women he would see was. He is uncomfortable around very flamboyant gay men. I've never been that way. I talk mostly like I'm straight. I don't show obvious signs of my orientation. Not really out of fear. More of I know who I am, I don't need to flaunt it. I do look a little feminine though. Long hair, short and petite. Skinny jeans. But that's about the extent of it. But back to Joe. As I said, he has had many girlfriends, but he would always eventually talk to me about all these things he didn't like about them. Then a month or two later, they would end up breaking up. I always just assumed it was just relationships that didn't work out. Nothing more.

It's been 5 years now, since I fell in love with him. I have went through so much pain and depression over the course of that time. I've lived with him on more than one occasion. I even tried breaking myself away from him. I managed to for 6 month but I was so broken. I didn't see a point to even keep carrying on without him. Then he reached out to me one day and we became good friends again just like that. I accepted that I would never be with him. I would rather be his friend and be there for him. I'd rather see him be happy than to tell him how much I love him and see our bond dwindle away until there's nothing left to hold on to. I simply can't live without him. He gives my life meaning in an otherwise meaningless world. And I couldn't do it to him. I'm basically the only friend he has anymore. And him and his current girlfriend have told me about how depressed he was when me and him weren't talking. Even if he doesn't love me like that. I do know he loves me. And that alone is enough for me to sacrifice my own selfish love to see him smile.

But it just seems like things are different recently. Joe has a girlfriend now of 2 and a half years. They have a baby daughter together. But here's the thing. I live close to him now, and we literally see each other every single day. I will drive to his house and just hang out with them, watch movies, joke around, help out with stuff. I enjoy it and with the many things I've been dealing with, it's been my only source of happiness.

But lately, i've been noticing subtle signs he shows towards me. He always teases me, always. And I do the same to him. We've always argued like an old married couple, but I notice it more now. And he's doing the same thing as he's done with his past girlfriends. He tells me about how lazy she is, and how she seems uncommitted. Or how stupid she can be. How he's tired of all the drama from her family and how she doesn't see that things need to change for the sake of their daughter. He's just showing signs that he's not as happy as he was when he first was with her. While it hurts me that he has to feel that way, it made me realize the pattern. And the fact that I'm the first person he comes to about these issues. Or when he has a breakup, he comes straight to me. Just because we talk about everything. But every single day I am over his house just hanging out and spending time with him. I'll admit, a lot of it is me. But at the same time, he just expects me there every day. He definitely doesn't mind me being there. And many time's he's wanted me to come out there.
I don't know anymore. I can't tell if he has feelings for me, but he's extremely conflicted about the general aspect of liking a guy. Like, he has a family which is what he's always said he wanted. And he was raised in an extremely conservative family who would disapprove of him being with another guy. So maybe he has that fear too. Because I don't know of any other people who are friends and are as close as me and Joe are. That are as big a part of each other's lives as we are. The only thing that is lacking is the physical side. I think some of that is me tho. I make it a point not to make my feelings known so I refrain from being touchy with him. Especially with him having a girlfriend. I hate cheating so I wouldn't contribute to one. Honestly, now that I think about it, he touches me more than I do him. Not affectionately, more of playful, but still. Or maybe I'm just bat shit crazy and I'm imagining him growing feelings towards me because of my feelings for him. I just can't tell anymore. The way he looks at me sometimes, really makes me wonder, though. And it's honestly eating me away inside. I wish I could just tell him without ruining anything. Maybe just the fact that he knew how much I love him would make me feel better. Or that it could give him an opening to tell me how he feels. But at the same time, I know Joe. He could just say no, then slowly stop talking to me. It would be damaging to him, but he does have a family and having your gay best friend over who is in love with you every day could make things a bit uncomfortable for him. I'm so confused, and I want things to work out so badly. But I can't lose him. I don't care what you guys try to tell me, that I would feel better, it would be best for the both of us, I don't care. I won't lose him. If I have to spend the rest of my life sacrificing my happiness for his, I will. But I just want advice on whether or not you guys think that he could reciprocate my feelings. I know I kind of spread all of the signs I've noticed out, so I'll make a little recap list.

We see each other every day
We have many years of history
We text each other all the time
He is showing signs of being unhappy with his current relationship
He could have fear of his real feelings.
He gets kind of touchy with me, nothing crazy tho,
I know he would do anything for me.
We are teasing each other 24/7 (Not exaggerating.) I think we do it to cover up how we feel. At least I do.
He has asked me if I wanted to move in with him and his girlfriend on multiple occasions.
I honestly think he has a slight suspicion that I like him. But doesn't do anything about it.
We always get along despite how much time we spend together.
The way he looks at me sometimes is questionable.

What do you guys think I should do, here? Should I tell him how I feel? Or wait to see how things go with his gf? I wouldn't tell him in hopes they break up. More of just so he knows how much he means to me and how despite how he feels, I want to always be there for him.

Or should I just not tell him ever, and do what I currently do, just keep him thinking the love is platonic and ensure nothing changes between us unless he gives me obvious signs he likes me.

Just please don't tell me to stop talking to him. I've seen that so many times on here, and I'm telling you I won't do it. I need him and he needs me. Even if his isn't on a romantic level. There's just too much history.

I just need to know what I should do. I think between the two of us, he would be happier with me. But that could also be my feelings playing tricks on my mind which could be the root of all that's happening here. But you guys tell me what you think. Cuz I'm so tired of the confusion.

 

I really want to. But I just don't know when it would be a good time to do it. Like I said, he has a girlfriend, and while things seem rocky between them, I don't want to complicate matters for him more. Maybe one of these days I'll grow the guts to leave him a letter just basically saying how I feel. Or I could just get him really drunk and tell him to where there's a change he could be more open with how he feels in return. Thank you so much for the quick reply, though. I definitely needed an outside opinion on this.

 

Honestly, she's asked me too because she's my friend. But she's also not the brightest, I hate to say. And if Joe has feelings for me, he's pretty good at hiding it. I think that she just assumes me and him are basically brothers and she never minds me being around because I help them both out with stuff. That's why I hate feeling like this and why I'm having a hard time telling him. I don't want to ruin either one of them being happy with each other, even if Joe is getting tired of things she does. I don't want to be the one that ruins it. The biggest thing is he has a baby daughter which would drive any couple to stay together. And I don't want to be the cause of a family splitting apart.
