Does it sound like my RA's into me or is she just really friendly?

umm, it sounds like to me that she likes attention, and you need to be careful, because she could be messing with your mind. Just be careful, if you like girls that OK and if don't then, don't worry about it. She is probably testing you, to embarr you or she too a shame for what she likes or does in your private time. Just let it go..don't worry so much about it
