OK, so I have these two chicks friends of mine. Chick A we'll call Carmen and girl B we'll call Michelle. I just picked two random names because the last time I tried something like this, people compared it to the unibomber manifesto.
So I met Carmen and Michelle way back in September. I thought they were both pretty hot, and I asked my friend who he thought was hotter. He picked Carmen. So, being a chauvinistic pig, I decided to get closer to Carmen, if only because she was prettier.
I became very good friends with both of them, and had a crush on both of them. I ended up really liking Carmen, and talked to Michelle at great lengths about her, and she ended up telling me about the guy she liked (but thought was gay)
Me and Carmen ended up sleeping together a few times, and I still really like her. Things ended up being put on hold after her ex tried to off himself, although we hooked up once after. Things are indefinitely on hold again. We're talking a lot still, but we're not doing anything. I can feel the tension building, and indeed, it feels like we're building up to something, but I dunno. She keeps telling her friends (who I'm also friends with) that she likes me, and she tells me this, but nothing still ever happens. So...

Carmen is one of two girls I've ever really liked ever. The other one I dated for several years. No, I'm not the type of guy who falls for every girl he meets either.
So now this Michelle girl. I don't know what her deal is. We talk every day via text, IM, phone calls, you name it. I joke that she's my backup wife.
When we walk somewhere she holds my hand, or puts her arm in mine as we walk.
We went out to eat recently and her boobs were hanging out, and she was kind enough to point it out to me several times.
I had a party recently and she ended up dragging me around to different areas by my hand. Later she tried getting me to change my facebook default to her kissing my cheek, and then said nevermind and told me to use one that featured the three of us. (Carmen, Michelle, and I)
Today she tells me that her boobs did infact look great on friday. Then she sends me a picture of herself in her underwear and a t-shirt asking me what I think of it. I told her she looked hot.
So I do kinda like this girl but here's my problem.
I'm pretty positive she's hitting on me...
but whenever I suggest anything, usually jokingly, she usually says its weird because we're friends or that I'm like a brother to her or whatever.
Am I missing something here?
Its 4:40 am and no one on my buddy list is awake except for drug addicts and her so I turn to TB for sage wisdom.
