WOW! Your husband sounds like a gem! I am sorry he is being so difficult. I don't know a ton about this subject only experiences with some friends but I do have a couple of things to through out there. First of all, it is hard to understand why ANY father would want their children to be mother-less! Unless you are abusing your kids or abusing yourself with drugs and alcohol, it is hard to fathom that you not being in the picture is a good idea. Some encouraging thoughts are that as the mother, the courts tend to lean in favor of the mother (unless there are extreme problems with the mother that endanger the children).
You need to not have one defeating thought, get out there and find a job and housing IMMEDIATELY!!! Don't let this guy run your life or take it away as it were. Find friends or family that can help you pull through the next couple of months so you can get stable. Do not give your husband any reason in the courts eyes to take your kids! They need you and you need them.
Be strong and GOOD LUCK!
