Trying to let go...

This guy took my virginity a little less than a year ago, and we've been "friends w Benefits" 😜😋ever since. However we aren't friends anymore...like we don't smoke and hangout like we used to...and the only time we talk is when he's trying to come over. I told him it bothered me and I noticed during sex he became WAYYYY more intimate and after sex he wanted to just cuddle. 💕💕💕I don't think he really cares about me tho and I've been trying to let go but he's all I think about 😕😕😕😕😕 there's not a SINGLE DAY tht I dont think about him and Idk what to do at this point. Pls help 🙃
