Search Results: touching and interest level

A quick back story: Met a girl on a 14hr plane ride. We sat next to each other and hit it off extremely well (lots of touching and flirting). We took a taxi ride back together since we live so close. During the taxi ride I was literally just about to ask her out but she revealed she had a boyfriend right after his call inturupted me (she actually lied about being in a relationship for the entire flight, she mentioned him a few times but only as her friend or flatmate). I told her that I was actually just about to ask her out and that I was interested in her and that I wish she was single (she took all this very well and was noticeably happy when I told her this).
She revealed to me that she was about to breakup with him in the next couple weeks and it's something that she's been thinking about for many months now. She didn't want to give me her number because it would make her feel guilty for cheating, but said we could be facebook friends since that's not cheating (also, I wasn't going to ask for any other manner of contacting her after her saying no to giving me her number, she said fb friends after a minute had passed because she said it would be good to have a way to keep in contact for the future). A week later I sent her my first message. She's been taking a day or two to reply to my messages which makes me question her interest level, but then again she's the one that initiated a meet up. I guess her taking so long to respond is really throwing me.

PS I know EXACTLY what I'm getting myself into and the type of girl she is and I'm fine with that. I'm not naive and fully expect and are prepared to getting burned in the future if something does develop.
