My husband refuses to separate himself from his parents and siblings. Should I divorce him?

[SistaGrl]

They own a family business and come from a small (gossipy) town. I moved from my city and job to be with him but he refuses to give up anything in his old life for me. We were in a long distance relationship for a while and when we were together then it used to be just the two of us. Now after 6 years together we are married, own a home and have a two year old daughter. Everything that means anything to me means nothing to him. He refuses to establish a new life with me and tells me he's not interested in changing anything about himself or his life. His parent's think what's ours is theirs and he believes that if we shouldn't make any plans or purchases that don't include them because it's not fair if we have something they don't or enjoy life in a different way than them they will be upset and say we think we're too good for them. We can't go anywhere without seeing them or or being asked personal questions about our lives from someone they know (because my husband tells them everything and they tell everyone they know everything because they love to gossip and brag). My husband refuses to make any plans for our future without consulting them because he refuses to think for himself so I don't know what he really wants because all his decisions are influenced by them. His mom has even gone so far as to try to be-friend the friends I have made so far in order to make sure they are invited to everything we are so they can be there to control us. I have taken care of myself by myself for a long time and I'm very independent, but my husband didn't move away from home or have a girlfriend until he was 26 and that was me. His mom still does paperwork and pays bills for him and his whole family acts like we are obligated to attend every holiday, birthday, Sunday (Church), etc...etc.. with them and if we don't show up they give us the silent treatment the next time we see them. Every visit to spend time with my husband at work turns into a visit to see them too (the business is next to their home). I can't even have lunch with him without them showing up. I have talked to my husband and he refuses to discuss anything with them and he refuses to stop stabbing me in the back. I have talked with them about things many times over the years (because he refuses to stand up to them and tells me not to put him in the middle of it) and I have very nicely and thoroughly explained my issues with them and politely and directly asked them to back off but they won't do it. On top of that my husband refuses to back me up on it and makes it know that he sides with them. He even tells me they know who the problem is and it's not me (him). Now I'm like an outcast in my own life because not only do they treat me like a enemy trying to come between them and their son, my husband sides with them and blames me for all of our problems. He refuses to tell them no even when he's the one who doesn't want to do something and he'll even go so far as to blame me when they ask him why we didn't show up. He refuses to spend anytime with them without me present so if I tell him I don't want to visit them he refuses to go alone, then his parents start calling and calling trying to find out where we are and he refuses to answer the phone to tell them we're not coming. Even when I tell him to just answer and tell them we're not coming he says they know. (But they keep calling.) They won't accept no when it comes from me and he never tells them NO. So the next time we see them they are all pissed and acting all victimized giving me the silent treatment. I'm so tired of it all. I'm tired of coming second to them and I'm tired of even having to hear about them or see them. I feel very betrayed by my husband and I just want my own life again but I love him and want our marriage to survive for our daughter's sake!!! What do I do?
(Sorry So Long!! ) I agree with those of you who said I knew what I was getting into, but it doesn't really bother me that he/s close with his family. I have a family too that I love and care about, but I make sure I have a relationship with them whether he wants to or not. I don't expect him to give up his whole life for me, but why don't we have a right to build a family like the one they have without their input (Redneck_momma) By the way his mother sabotaged her husband's relationship with his entire family. I do not wish to do that, I want him to have a relationship with them, but I do not wish to be pigoeon-holed into spending time with them just because I'm married to him. They are his family, not mine.
