HELP Is my marriage over?

I have only been married for 3 months. My husband and I bicker constantly. Sometimes, it has been serious. Usually it's over things that what most people would consider to be mundane. Several times, I have asked for a break or for him to leave-he refuses. It results in him making suicidal and other threats where I have to tell his mother and then his whole family gets involved- very embarring for us. I don't even want to face them anymore, and I get along with them fine. I'm realizing that my husband tends to make threats to harm himself or put himself in dire straits to get attention.Tonight, we had some arguments. We are not seeing eye to eye. We've talked about things and have not gotten anywhere, it always leads back to this argument and confusion. He refuses to attend counseling with me. Also, he pulled another stunt tonight, no one knows where the hell he is. I had to call his mother at 1 in the morning to tell her. This is going to kill me but I can't keep taking this. I love him and I'm sure he loves me, but I'm tired and don't know what to do at this point. We're in our 20s and have no children.
