Updates....it hasn't changed much

In the Two years since I've last written, and sadly not much has changed. It got better for a short period of time, but then I became pregnant with my daughter and how things are no better than they were before. They had gotten so good and so many promises were made after he came back that I really thought it all would stay good and he had really changed. But tonight alone he has been so disrespectful, cussed me out, called me names and thrown a swing and a dip can after telling me "fuck you". His selfishness also hasn't changed and that is the hardest to swallow. Our relationship is still all about him when it comes down to it. I am contemplating divorce and I hate that because we have Two children together who need us. All of this happened because I went in for a consult about getting a hysterectomy instead of tubal due to my precancerous cells and he asked if we couldn't wait on the surgery after being told that I won't be able to get around and help with the kids for two weeks following the surgery. It makes me feel as is he would rather see me develop cancer than to suck it up and let me have the surgery I need. I feel so unloved and that he doesn't care at all. He was willing to be out of commission when it was for him(for back pain, a spinal block) but not for me to have the surgery *I* need?!?! So I called him selfish and told him it made me feel like he didn't care. Well that set him off resulting in yelling and him throwing his temper tantrum because I "made him look like n uncaring POS) well sometimes the truth hurts!!! He walked out in the drs office and left me alone for my pap smear which was very painful and thoroughly embarrassed me by walking out. I just don't know and can't imagine leaving him no matter how mad I was while he went though a painful procedure and I wish that for once, he would do the same for me. But when he's angry he doesn't care about anyone or anything except himself and throwing a tantrum to let you know how angry he is. I just so wish he wasn't like this and I don't know what to so.
