Breakup..

I was seeing this guy for over month and things were great. We were close and happy. We talked everyday, then out of nowhere, he blocks me. He didn’t give me any indication that something was wrong and now I feel like shit. I already have low self esteem, so it was hard for me to believe he was interested anyway. I keep thinking that he was using me or that it was some running joke he had. Or maybe I wasn’t good enough to be with him. I don’t know how to make myself feel better.
