At this moment I feel like I can't get over this...?

My husband called me the "c" word (you know the word you just don't call a woman unless you catch her cheating on you or something) tonight over the dumbest thing and he was totally serious about it!! We have a fairly good relationship for the most part but he has his issues for sure! Just the other day he came home from the bar drunk off his butt and was throwing up all night, hungover most of the next day. He almost 36 and I swear he needs to grow up. We have a 15 month old, and what is haunting me even more than my husband calling that word is the look on my poor little guys face when he saw mommy so upset and when my immediate response to me husband was yelling at the top of my lungs to never ever call me that again. Anyways I swear after his antics the last few days I'm not feeling very happy with him and I'm super mad at him. What should I do?? Just get over it and make up with him or should I not tolerate that kind of thing from someone who is supposed to love you?
