Ending the friends with benefits

So I lost my virginity back in February to a guy who later told me he wasn’t looking for a relationship and didn’t want to be exclusive. I kept going along with our friends with benefits situation even though I kinda had feelings for him because I liked hanging out with him and I was high key enjoying the sex. Last week he said “we need to talk” and then totally blew me off when he knew I was waiting for him to to get off work so we could talk. Today I found out that he slept with someone else that we both work with so I’m backing out of the whole situation. I’m super bummed but I was not invested in it but I just needed to rant. Also who else thinks this is uncomfy to the extreme holy shit 🙄
