I know I was wrong and I apologized many times but to no avail (not all were entirely untrue). He has broken up I the past with me many times over silly reasons. Is he justified to do this repaeatedly

It sounds like the best thing is for both of you is to go your separate ways if you keep breaking up and getting back together without having worked through the problems that caused the break up. Apologies are not working through the issues. Talking with each other, setting boundaries, and be open about problems and concerns is.

Justified or not, the revolving door relationship isn't good for either of you. You can close the door the for good. Allow yourself to heal and move on then find someone who is willing to work with you to build a relationship.

Seems you've become a victim of your own thoughtlessness, and in view of this it would seem you've lost your b/f.

Ive been guilty of speaking from the drain instead of the brain myself, and its so easy to do, but almost impossible to undo, we ladies can at times breathe fire, and yes it burns, some of those heat of the moment remarks burn the other very badly and leave scars.

I think as Cat has already said, it looks like its time to call it a day, unless you and your b/f can sit down and calmly talk about the cracks in your relationship, if not then all you will be doing is on and off like a light switch, you or anyone in a relationship needs to face, accept and deal with those cracks or deal with whatever caused them together, or you can ignore them and go back to on and off until doomsday, but the relationships, stuck in broken mode.

However if you sort them out together, you do have a chance of moving forwards in the relationship, but so many young couples don't even attempt it, a few kisses Im sorry and I want you back, does not a relationship mend.

Im sorry your time with the b.f has come to its end, it hurts now but you will heal you will get over it and you will move on and in time you'll get into another relationship, just take what's been learned from this one into the next, and who knows that could be the one you stay with indefinitely. Good Luck, and Im thinking of you. So sorry you're hurting.
