Why is he staying with me if I am all these things

been with a guy for 5 months now. We are engaged we moved fast he told me he loved me 2 weeks than we got engaged 2 months later it's been great until a week ago he was acting distant finally he told me what was wrong I am shocked I didn't know hr felt this way he said that I was to needy that I was suffocating him that that I worry to much that I am an emotional disaster that if I layoff and don't suffocate him we will be fine that he is not going to consume himself with me he has other responsibilities that I am always complaining that if I am not the man I want that I should break up with him I don't want that I told him than break up with me if you don't like the way I am He said no I am not going to break up with you if he isn't happy with me than why won't he break up with me
