Men please help a girl out.

My husband will watch porn after we have sex even though he has cum. He adds random single girls on facebook every Saturday night when he has had a few but just shrugs it off as though there is nothing to it. I have an issue with porn (some people are fine with it but I'm just not) I asked him not to watch it anymore but he hasn't. He has also called me another woman's name while trying to have sex with me when drunk. Now I am not an idiot I know this doesn't look good but can a guy please tell me if this is something you have done innocently or is it time to say goodbye.
