2nd time around...should I go?

I pretty much know what to do but am finding it very hard to make the decision. I divorced my current husband in 1998. I remarried him in 2001. When we first married I only knew him for 6 months. I guess you could say we don't know much about each other. There have been good times but more bad times. We have three kids together and I know they would be much happier if we were apart. I have been through my share of drinking, drugs and cheating with him. I don't think he is cheating on me but one never knows! I just recently got a huge promotion at work and he resents it. He throws it in my fave every time we fight now. He is a very jealous and possessive person. He tries to control everything I do from what I wear to what time I go to sleep. I feel like I am trapped! And then other times he treats me like I am his mother. I have to wake him everyday and remind him of everything...even to pick the kids up from daycare! I am doing everything alone anyway so what do I really need him for. I have stopped crying about it. I think I am to the point where I am so fed up I am mad. I just don't like him anymore and am so tired of everything. All he does is tell me he loves me when we argue. I have told him I want a dvorce and he just laughs at me. I am concerned about the kids and what will happen if I don't "get" them. He is a good father but on;y when it is convienent for him. Any advice would be awesome. I am in Texas and the laws here I am not at all familiar with. We were divorced in Connecticut the 1st time. Thanks!
