** Re:My marriage and my husband

I am a 23 yr old female in Alabama, I don't have to many supportive people in my life. I have been married to my husband for 3 yrs we have been together for 4 yrs. I have 3 young children boys, 5, 3, & 2. I am always overwhelmeed to say the least but the domestic life is what I want. The problem is with my husband, I may possibly be pregnant again, I had my first child at 17 and didn't have a chance to finish high school so I have no education although I am farely smart when it comes to academics. I have planned on taking me GED test and going to nursing school but the constant care of my children and my lack of help hasn't permitted me to do so. The only financial support I have is my husband who left me just 3 days ago. I am scared to death and to say the least extremely depressed. He has a past of alcoholism and drug use, I do not. He is a pretty good father and provider or so he has been for a while. I stay at home all day and clean while he works but the problem is that he is a perfectionist, I was cooking dinner and he walked by and made a smart comment to me about leaving a candy bar wrapper on the counter which insulted me beacuse I do ALL the housework and I do the best I can. It just really hurt my feelings b/c he never notices anything I do he says "it's my job" and I by no means keep a spottless house with 3 toddlers! but I keep it cleaner than most anyone I know.. I like a clean house but I have had to lower my standards some since we've had 3 children. But it is by F-A-R nasty. Well, I just felt TOTALLY disrespected by that comment so I made the comment that he leaves things out all the time that I throw away and I always pick up after him! He wouldn't hear it, he put his earphones in and said "no I don't" I don't know if he's trying to but he really makes me feel worthless and unappreciated. The next day when I talked to him at work, I brought up the fact that he makes my son from my previous marriage do things like "clean his plate" when he doesn't do the same with his son from his previous marriage. He says it's because he only sees his son every other weekend.. but I just don't think it's right to show a differance.. am I wrong?... He has left me previously before SEVERAL times and the tim before this he tried to pick up a girl... he still denys it even though I have numerous wittnesses and she even told me he did it herself. He said going to bars was justified b/c I threatned divorce. I love him and I really don't know what to do... mainly b/c of my poor financial situation and my children.. we don't always fight but I know all of this probably sounds like childish rediculoussness to you but he won't return my call even though I have tried to make amends. what do I do??? Should I divorce him even though this is not what I want?
