I'm ashamed

Today I got in a fight with my husband and I got to angry to tried to hit him with an empty coffee mug. I instantly felt awful and apologized and started crying. But he doesn't care, he's pissed and I don't blame him. I did it because he's constantly pushing my buttons and trying to piss me off because he thinks it's funny. I've tried to talk to him about it but he just doesn't care. I'm not making an excuse for what I did but I just don't know what to do.
