Many years ago, I knew a married couple (just acquaintences) where they had been separated for a brief time, and the husband got a woman pregnant during that time. The woman had the baby and the couple got back together, working out their differences. The wife treats the child the same as her own. The husband has some custody/visitation, so the child comes over and is loved exactly the same as their other two children. I've seen it with my own eyes. It is possible.
However, chikeemomma, it sounds like your DH is abusive and you have a horrible relationship. I strongly suggest you start making a plan for yourself to get out on your own. Go talk to your county agency where you can get foodstamps/ subsidized housing/ subsidized childcare. Move into a cheap apartment. Sell the house if it's in your name. File for child support - even if you can't expect to get any. The child support agency will go after him on your children's behalf. He'll end up in jail for not paying.
