He is moving another woman in!

We are separating, although we still live under the same roof in the house he owned prior to our marriage. He has one room and I another, while I pack. This is his idea not mine at all. I was totally surprised by his request for a divorce. He disappears every evening after work and all weekend but he does come home every night to sleep. He has recently asked me if his ex-wife could move into our back bedroom. He states this would help monetarily. He is very controlling and although I have said no, he may do it anyway. Oddly enough, she moved to this area 5 month before his “surprise”. What can I do? Will any good come out of this for me? I am totally unable to leave the residence at this time due to lack of substantial income.

Do you have a specific question related to your situation?
