I have become the crazy ex gf

My boyfriend broke up with me citing reasons of being out of love as he is not the guy that I want and he cannot make me happy. But I am not able to accept the breakup. He makes me happy just by being there. He doesn’t need to do anything. I don’t know why he feels he cannot make me happy. I tried a lot to convince him to get back. But he refused. We still talk because he doesn’t want to abandon me when I am so low and emotional. As I am unable to detach. This relationship was the most important thing to me. He has given me full permission to talk to him, meet him whenever I want. And he has also told me that I can go no contact or block him without any explanations, he will understand. He told me he is in mood to date anybody for a long time, so i needn’t be worried about that part.

Now comes the crazy ex gf part. Just yesterday I saw my ex with a girl in a bar. I went up to him and gave him a really s*xy hug and kiss right in front of that girl. He didn’t say anything bad, just smiled. Then I faked that I just noticed the girl. And he introduced me to her, she was a friend from work.

I feel so embarrassed. I thought he was on a date and I was jealous. What am I doing. I still feel I am in the relationship. I want to have him back. I don’t want to move on. :-(
