Should I ask her out? Argh, you'd think this would get easier with age!

I would too! I have a three strike kinda rule. That would be a Strike 1. He/She's not into you. 2. Would be your next advance 3. Would be the last. If you strike out on hanging out three times, it's not gonna happen. Nowadays, I consider the fact that a guy doesn't text me a strike lol. You can never tell when someone's just trying to be nice and not hurt your feelings. But I'm a big boy, rather sooner than later. I talked to this dude for 3 months before I had to just end whatever the fuck we were doing. He was okay with me building him up and cared enough for me to tell him when he looked good, but never seemed interested in returning the same or cared enough to meet or tell me what was up. I asked three times too! I was like, are you attracted to me? He said he's not sure yet. Shit like that. You end up at square one so much. So if you start to take those things as strikes.. that way you pull out, erase numbers/info so you don't call them and just see how long it takes for them to get back to you. If they never do, there's your answer.
