The control thing is very common with people who come from troubled backgrounds. Particularly with children of alcoholic parents or parents who have extreme fluctuations in mood. I don't know your background other than you mentioned it being really ruff.
I understand now why you are trying to hold onto the house. It makes perfect sense. However I think you may be selling yourself short. Whatever happens you can handle it. It may not be the best situation but I can tell you are a very strong person. That is the gift that comes from having the struggles that you have.
Let me add one thing. Let's say you get to keep the house but it takes two years of fighting and as a result you are short, angry, or dismisive with your kids. Let's say you spend all your time thinking and planning and worrying about how to keep your house. What have you done? You've robbed yourself of the happiness of spending that time with your kids.
One thing I've learned is that happiness is around you not in front of you.
