In order to preserve my friendship like you said, should i just ask her as to why she did those acts of intimacy? or would this very question bend her the other way?....and should i just go ahead tell her how i feel?
You can kill a mood by shining a bright light on it. She trusts you and likes you enough to put her head in your lap. If you start asking her about it, she may feel embarrassed...and there's a good chance she'll feel self-conscious, and stop.
In other words, I think there's a pretty good chance that asking her why she did it would indeed bend her the other way.
As for telling her how you feel, I'm not sure how you feel; you didn't say in your original question. I can guess that you're interested in her, maybe even in love with her. That would be natural.
But I tend to recommend against surprising a girl with a declaration of love, even in a case like yours where there seems to be a good chance she'd reciprocate. If she says she loves *you*, then by all means go for it. Otherwise, my guess is that you should leave a door open to preserve your friendship with her, just in case.
But I may be wrong. I always took the coward's way, and ended up not dating until I was 33. So keep that in mind; I could be wrong.
Still, I'd think that just asking her at some casual moment if she'd ever date someone like you would be a good move. Or ask her "do you think we'll ever date?". Just make it casual enough that if she says "probably not", you can both laugh it off.
And don't wait too long; one thing I can tell you for sure is that if you lose touch with her without exploring the possibility of romance, you'll regret it forever.
Another reason not to wait too long: if you're with her for too much time without letting her know that you're interested, you run the risk that she'll pigeonhole you permanently as a friend.
