Can some married people help me out of hot water? Don't know what to do.?

If you are not married and if you only want to attack people please do not answer. I hate to ask this, but I need some experienced help. Ok, I like pretty things. Right now, I am on partial leave of abscence from work until the baby is born. Anyway, I have two credit cards, my husband has three, one with no limit. I went shopping for clothes and jewelry, well I spent $3,8000 and put it on my husband's card. I am usually home all the time, but yesterday I was at my family's house and could not get it before he did and hide the page with my charges. He is livid, I don't think I ever seen him this mad at me. He left and came back about 4am reeking of booze still talking about the crazy woman that he married.He slept in the guest room and refuses to talk to me. Its not like we cannot afford it. As I pointed that out, he got even angrier. He told me to shut the h*** up. He never cusses me. I am starting to get emotional and I want my calm, loving husband back.
