rahner's story

still confused

I only discoverd my ex was an N about 3 months ago. I never knew as he was the perfect partner for 13 years other than he with held sex from me for the last 5. His excuse was that since his heart attack at 40, he had no drive but would work on it. Well, I now now know he was lying as he was masterbating all the time and I have suspitions that he was having phone sex and maybe prostitudes. Mine out of the blue, just had an affair with a younger woman that has 3 kids ages 7,9, and 12? He is 55. I was devastated.
Anyhow, I kicked him out the night I caught him on the phone with her masterbating and he moved right in with her. I don't understand when she lived 5 minutes from our house that he never left here to be with her? I honestly thought it was over, he did say it was only an emotional affair due to his problem. I believed him because he never wanted anything to do with me sexually for the past 5 years and he was so convincing.
When he moved in with her of course he lied. He told me he was livng elsewhere and that he was sharing a house with three others and her. He said she was nothing but a friend and it was not whatI thought. He said he did not love her and was not sure if he wanted to have a realtionship with her but told me numerous times it was over with us. I came to find out that he infact lied about where he lived. He lives 5 minutes from our home and with her and her 3 boys. Since I discoverd the truth about her, he stopped coming here to help me get the house ready to sell. I can't get him to take his belongings either and he still texts me at work in the mornings to tell me to have A GOOD DAY?
He is driving me crazy. I am seeing so much of the N now that I have never seen before. He is turning out to mean to me now and is still lying to me all the time.
Last week I was talking to him about signing the seperation agreement when out the blue he says "I have no place to go"? Say's he will not marry her and does not love her? He actually told me he is still not having sex with her as his problem is still there? All lies!
I guess my confusion is why he won't let me go on with my life.
He has been gone since the middle of may and with her. He seems to be settled in with her as I still get the credit card bill and he is racking it up now like never before. He also has racked up his line of credit and it is mostly on liquer (says he doesn't drink anymore) and food, and entertainment. What I do not understand is that a few weeks ago he signed a seperation agreement giving me the house(was mine when we met) and all the belongings in the home. He was willing to give me 375.00 every two weeks for 6 years for support and 4000.00 of half our savings. I found out that this agreement was not what I needed to register in court so I needed to go through a lawyer. This cost me 2000.00 but it was the legal way of doing it. A week ago I gave him the draft of the new agreement and now he will not sign it and has ignored me. He has said now that he wants to go to a lawyer. He has completed cahnges his mind now and wants to give me nothing? I wonder if she is behind this even though he tells me she knows noting about his private life.
Here is the real confussion.
I told him two months ago that I wanted to selol the house so I could pay of my bills, by a newer car and get on with my life. Told him I would never have to see him again or ever speak to him and he could get on with his new life.
He is also signed on to my mortgage as a co signer for another 3 years and if I sold the house that would free him of that also. Now he does not want to sign the agreement for the seperation where spousal support is 750.00 a month, yet he continues to pay me 3000.00 leaving himself with almost nothing? I don"t get it? He loves his motorcycle and wants that which he gets once the seperation agreement is signed, yet again, continues to pay me 3000.00 on his own doing, and loses out on this nice weather to rise his bike?
Can anyone put some light on this for me. I just don't get it. On weekends now I never hear from him or in the evenings, yet he will text me in the mornings to have a nice day? Come by the house to mow the lawn and came last week to put the air conditioner in? What I I dealing with here?
Need help!!!
