I may have a new relationship with someone confused about their identity. Please help!

Hey- it's been about a year I've been on since my bro found me on this site and it became a mess, but if anyone can offer advice, I'd be grateful. Feel free to skip to the last line if I go on a bit. Sorry.

So I've been grappling with my own gender identity a bit, but I think I'm a lesbian, and about a year ago I found out that my friend thinks she is bi, and we both said that we were crushing on each other. Speaking for myself, I think that once I suspected I was just desperate for some validation, and so having a mutual "crush" would be more evidence if I could get myself to believe it, being in a religious community she's the only other questioning person I know. I strongly believe she did as well, but didn't want to realize it. Ever since I've accepted I probably won't know for sure until I'm in a more serious relationship, but I've always used lesbian porn- sorry for the unnecessary information. We stayed in the same circle of friends but only really were linked through that, but at sleepovers for truth or dare and such I've asked her what her type is, and she said something along the lines of "you know, girls and guys." Clarifying myself I asked again, but she just seemed kind of confused. Not to insult her, but she's a person who seems to think of herself not quite in the spotlight but really just in having to fit certain feelings, a kind of slightly superficial drama she hates in herself and occasionally grates on my nerves myself, though I've never mentioned it, of course. Last night, though, at a friend's sleepover, all our friends went upstairs for ice cream and we just stayed in the close position we were in for the movie, and we got to talking. She told me she still likes me- I won't really say exactly what for her sake of privacy, but something she said made me think she was convincing herself of that to fit her self image. We kept edging closer and though at that point I'd admitted that my previous feelings towards her were forced, I leaned in to kiss her, and we French kissed. I was extremely turned on but felt like an asshole when we were done, but she seemed to be faking passion and dropped another line. Loving her in that moment, I played along, and I'm ashamed but we kissed a few more times throughout the night.

So now I think that I may be caring about her as a distant friend emotionally and being sexually hungry for the only gay person I know and therefore using her as a resort while she is sexually confused and trying to figure things out. What can I do? I feel like a terrible person to speak my mind and bring her pain, don't want to lie to break things up, and am just a flat out terrible person if I keep going romantically. It's not really that bad though it sounds that way written down, but please, give me some input. Thanks.

 

Please help, sorry, I should have posted earlier but I'd really like an answer before I see her at school tomorrow.

 

Thanks- reading back I made it sound pretty awful, it was actually really nice, afterwards I just started stressing! Thanks again!
