Divorce Support Forums: Temporary Support

I am really upset. My STBX of 25 years left me for another woman. He moved in with her. Claims that they are not romantically involved. He had a very public relationshiop with this woman that eventaully caused him to quit his job. He is now on his 3rd job in 4 months. All summer he was trying to force me out of our home. He offered me what he calls his "sweet deal" where he was going to pay for an apartment and pay my expenses for six months. When I asked him what would happen after 6 months, he said I would be on my own. I have since found out that his intention was to move his little honey into our home and build her a barn for her horses. 2 days before our 25th anniversay, while visiting friends, he told me that he didn't love me any more. After soloiciting advice from friends and a lawyer I was advised not to agree to the "sweet deal". I work but at a low paying job, which I love. I had no money for a lawyer, but after doing some research was able to find one covered under a grant program. I filed for divorce. Which came as a suprise to him as he thought he was calling the shots. Last week, we went to court for a hearing on temporary orders. We have a $1300 a month mortgage, he has not paid me anything since he left on 10/13. I was granted only $152 a week. I also provide a home for our 19 year old daughter who is a full time college student and employed full time. I was not allowed any child support for her. He has said he does not care if the house goes into foreclosure. The mortgage is currently 2 months in arrears and the order to pay goes into effect today. So, apparently I am responsible for the 2 months in arrears as well as paying the current payments. My monthly salary does not cover my expenses. My lawyer does not feel he made a full disclosure of his earnings. So now I have a mortgage I can't pay, but I have to provide a place for my daughter to live in. He went out and bought a new truck, While his daughter and I face homelessness. I gave her the option to live with him and she said she did not want to live with them.I spent almost an entire day calling the bank, working with non profit counseling agencies and local housing agencies. I have gathered all paper work and sent it on and am now just waiting to see what happens. Tonight he brought the first check by and when I asked when he would be coming by to clean up the cellar(90% of the mess is his) as well as the various messes in the yard. He said his lawyer told him that unless I agree to sell the house, he has no responsibility as well as no intention of cleaning up the messes. In court he claims no romantic relationship with this woman, although he lives with her, claims I told him to leave and many other untruths.
I am so angry. I could and have screamed. I am going to therapy. I can't believe that someone I lived with, loved and thought the world of for 25 years could treat me this way.
Any ideas or suggestions?
