I feel dumb

I was talking to this guy for some time over a month. We would talk everyday and hang out a lot. Like I was started to get interested in him. We held hands and kissed and all that good stuff. We didn’t have sex or anything but 2 days ago we had a hot and heavy make out sesh we were getting all touchy feely and like an idiot I gave him head. Today he tells me he feels he is being forced into a relationship as that he misses his ex. Like wtf why wouldn’t you say that before hand. I literally did nothing with you for the fact that this could happen. It just makes me feel so stupid and sad. He says he didn’t want to hurt me but I’m hella hurt. Idk why I feel like this guess I feel used. No need for hate comments though I know it’s my fault. I’m stupid 🤷‍♀️
