Let me say this. This guy still love you... But the prob is that you are too possesive. True love is base on trust. If you dont trust him at all, then there is no point going on the relationship. This guy come back to you because he know that you are the one for him and he had made a mistake. Trust take time and effort. But you never give him a chance. Think, if he doesnt love you, why is he still around with you and why wont he ask for break up. Now he really cant stand your behaviour and had ask for a break up. It is totally your own fault gal. Now ask your self. Do you want him back? There is still a chance you can get this guy back. But first your attitude must change. first of all, be his frend. then trust him. Try if you really love him. Dont bring up the topic about the other girl and dont bring up the past.
May god bless you
