Fear of Closeness

My boyfriend and I have had fights for some time now. I’ve felt he’s pushed me away and this last time he lasted 3 weeks with silent treatment. I told him I didn’t want anything to do with him and he sent me this message. I asked him to give me a few weeks to decide if I want to be with him again. We have been separated not talking and then broken up for a month and a half now. I don’t know what to do. I want to be with him but I can’t be pushed away and given the silent treatment. Am I not being sensitive enough?
