OP, why would you let him break up with you FIVE times? I mean I know you probably think you love the guy but where is your self-respect? What i see if that he thinks he can do better than you so he breaks up with you. Then realises he cant or that the grass isnt greener or that hot girl he had his eye on he doesnt have a chance with. So he comes back. And then decides that he wants to be single just in case someone better comes along. And then well you know. He breaks up with you again. If he comes crawling back for the sixth time, tell him to stick it where the sun dont shine. And mean it. Dont let him break up with you for a sixth time.
