Divorce Source: need help

I meet my husband in dec 2002. We married in may 2004. Be fore we were married I lent him over 15,000.00, rent,airline tickets, my engagment ring, a car for his ex,his storage etc. He told me to write everthing down and he would make payments.In five years he has paid back about 2000.00 of it.For the wedding and honeymoon of course he didnt have the means to help much with it $. We did our own and it was small. Ive owned my own home since 1996. But had moved in with him in nov 2003.I had a friend move into my home to help with the mortgage and keep an eye on the place.Hating the drive I had to make eveyday we moved back to my house after we were married.I refinanced my house and took money out 20,000.00 for remodling and things we needed for the house. One thing was a truck for him.. then things started to change.I found that he had took out 3 credit cards in just his name and maxed them out to the tune of 13,000.00 I took out a home equity loan to pay them off since not much of the house money was left, most of it went into his garage remodling.He was helping my brother fix his house so he could move, and when he sold it he would take the money my brother owed him and pay off the loan, well he had and accident with his truck and the money went to buy another truck. He spent alot of time in the garage and had alot of friends stopping by. I was suspisious. He went out of town so I looked in the garage and found drugs.My trust then went out the window. in 2006 he started cheating and got arrested with her in a hotel room with drugs. In nov 2007 my father passed away. just before christmas he went to see he son. He called me and said he would be back christmas eve. christmas eve and christmas day my ,fathers b-day, came and went without even a call from him. I was feed up. I changed the locks left a message on his phone to come get his things I was done.He never called back. then he moved in with a woman who had been coming to the house that I didnt know, four days later. he got arrested again for probation violation for his other arrest and went to prison for a year. we wrote and a thought he had learned his lesson by the things he said in his letters. He got out in Aug. and paroled to my house. things were good for a month then he started staying out late.And all through these years I was told how much he loved me and never ment to hurt me. I cant trust him anymore. He moved out, He told me he didnt what to hurt me anymore and now he wants me to lie to his perole agent for nine months that he still lives here. He said I had no right to lock him out in the first place. and that this is california and that he owns half my house. SOCIOPATH? I had made him sign a promiary note after I had locked him out the first time he wanted to get some of his things. I made him sign a promiary note that he owed me for the home equity loan, the loan before we were married , the bail I paid and the money he took off the credit card he stole from me that was only in my name that I had never used before. Which added up to 35,000.00 and then he could take what he wanted. Now my question is, does he have a right to half my house, half my 401k that Ive had for 22 years. And does he have to honer the promisary note ?
