Do i matter?

I love my man but lately we've been stressin I broke up with him. We've been together for 2 years and when I'm mad I break up with him. But we always break up he took that and ran with it. He somewhat of a thug but it's all good he's always faithful and we were always tied to the hip but we got into a bad argument and I broke up with him but i thought it was just one of one of our aguements I said some really really nasty things and he was gone for a week long story short I found out he was talking to another girl but he apologized for it should I forgive him or should I leave he never had sex just talked saying oh what did the girl look for a girl the girl said the same thing idk what should I do?
