So little background,me (f)male and my friend (m)ale became friends in college and its been two years since then,we met in a group project,became friends instantly and with other ,we chatted a little bit to get to know each other and we came to the point where we started having intimate conversations and we seemed to want more than chatting intimate things ,to the point on planning to hook up ,we met hooked up and we were fine,but it didn’t stop on one night stand ,we did more than one time and we continued to talk like we were a couple except we weren’t, it was fine from the start but I developed feelings for him ,we acted like a couple but we weren’t.sex ,romantic messages,dates we all did that ,non of our friends new what we did nor new that we were in contact .after developing feelings I thought that maybe its me having them late ,thought that he had them too ,because of how we treated each other ,then not far long he behaved too normal,like i was just a friend and when we hook ,he would leave as soon as we are done ,thought he was busy so I didn’t comment on it ,then it became frequently and I thought of asking but quote ,we are not dating.now am sure that he doesn’t have any feelings and just wants to hook up only and we go our separate way .my friends know him as we are in groups and I don’t want to be his friend anymore because of my feelings ,don’t intend to tell him cause ,he may say yes but i know he doesn’t have any feelings for me as i do ,and now i just wanna end it all and I haven’t told him nor do i know how to bring it up.
