After my BF and I have been fighting I will tell him how sorry I am. Usually he will get mad over little things and he will continue hurting my feelings until I beg for forgiveness, which I have to beg for a hour or more. I cry so much. I love him and when we are not fighting he is so good to me. What should I do?

Why do you let him treat you this way? Love isn't enough to allow someone to treat you like crap.

'which I have to beg.. '
Uh oh. No one has to do anything unless a gun is held to her head and she doesn't want to be killed.
You are allowing yourself to be a victim and you are not a victim, so just stop.

He is playing with your emotions, you are giving him control and he is learning how to manipulate you. VERY unhealthy relationships. It is one of the most basic red flags. You need to learn all the red flags and see how many he pulls. Usually where there's one there's more or more to follow.

I had a girlfriend that did something very similar to this. It took me a while to realize what she was doing and how wrong it was. I am better off without her in my life now.

This is someone that is not really worth your time if it continues. If he is good to you otherwise, then you need to discuss this with him and if he can't see what he's doing and hold back from continuing with it, then you need to tell him it's over. This isn't good for you and you deserve better.

Stand up for yourself when you are right, and don't beg for his forgiveness.

What do you fight over?
