she has a boyfriend, but flirted with me whenever he was not around. we ended up a few nights talking for hours, and ocasionally we'd meet up for drinks. on two of those ocasions, i leaned up to kiss her: first time she said no, as her boyfriend was sleeping in the next room. from then on, the sexual tension was pretty clear whenever we'd see or talk to eachother. second time i tried to get physical, she got shit scared (we'd been talking for hours about the possibility of us hooking up, and i got tired of talking =)) and made up an excuse to leave (she was obviously nervous). next night, she texts me and calls me about 20 times to meet up. i finally agreed to meet her outside her house, it was clear she wanted to see me and the interest was obvious. still, she was pretty nervous about the possibility of cheating. that night, i ended up sleeping in her bed, but nothing happened. fast forward a week or two, and she texts me about 2am to meet up with her and some friends. that night we ended up in my house, and we fcked like crazy for HOURS (and i mean everywhere, kitchen, bathroom, in my bed, living room, good, passionate, at times aggressive sex)... next day we had a social dinner where she and her bf were present. the weird thing is, i know the guy and, surprisingly, i get along with him fine. i felt like quite bad that night, felt like an asshole. there has been no contact with her ever since the night we had sex, i was never the one initiating text, and i keep refraining from doing so... what do you guys make of this? on one hand, i feel kinda bad, on the other, i kinda dig this girl, but i cant help feeling confused. the most obvious thing for me to do is to let it go, but i just wanted to know you guys' opinion as to why she stopped contact.

the night we fcked, i remember her saying that she wanted "agressive sex" from me, and wanted to feel "desired" again. its pretty clear that her relationship with her bf is far from being good, and, to be completely honest, it seems to me to be a pretty weird one. i wanted to repeat that night, the sex was mind-blowing, but i cant help feeling used, a mere substitute for what she might be lacking in that relationship she has...
