My ex boyfriend broke up with me about 4,5 months ago. First I did not hear from him for a while, then we saw each other for two times. After the last time, I told him that it’s all or nothing and that I can’t be friends with him. It was always him who asked me to hang out. Now he asks again, despite what I told him last time. I also heard that he was jealous that I hang out with a friend of his when I was going out. I still have feelings for him, but after every time I see him, I feel upset. I don’t think I can move on when I still see him. Does his behavior mean anything or does he really wants to be friends and is too selfish to respect my feelings for him? What should I do?
