Im a dumbass

My ex boyfriend and I have now hooked up three times after not speaking to each other for four months following our breakup. He broke up with me with no explanation in April and I really don’t know why I let myself sleep with him after the pain he caused me but i guess im just trying to feel the same connection but its not there and i just feel emotionless to everything in my love life these days. I have sex to just have sex and I don’t feel anything with anyone I sleep with. I desperately want someone to actually like me and have the same energy I used to give out but it won’t happen. Sorry for the rant. I needed to say it.
