Property division

I separated from my husband 12 years ago and the house was worth so much and now the price has gone up. My husband did not want to pay me support and he did not. I was married for 30 years he never spent money on me or gave me the money for kids. He told me when the kids were small that if I pay for all the house expenses, my expenses and kids expenses he would pay off the house. I paid all the kids expenses house expenses and my own he paid mortgage even for that he physically abuses me and mentally abused me and he had all the money and my money was all gone as I made less than him. He was a truck driver and had women out side. He made me lot of false promises and when I asked for anything he would hit me and call me names. once the kids were grown up I called the police he never came to get even his clothes as he had another house somewhere and he was gone. I stayed in the house and he did not sign on the mortgage and I went and got private mortgage. I have been working part time and paying the mortgage taxes and bills and now it has taken a toll on my health and want to sell the house. I called him many times he did not pick up the phone and the times he did he told me he wants half of the price now and i want to pay him half of the price at the time he left so which one he should get? I have not money to go to courts and fight what other alternatives I have. He worked as truck driver all along and has his money and my money went into the house so practically he wants half of my salary if I give him half of the money from the house. In the mean time he got both of the kids got married and I was not part of it even in the house he cut me out once the kids grew up and everything in the house was for him and his family and now after separating it all came out. My son met me in Tim Horton to tell me that he his married and the father came along with him. He controlled my son conversation and my only was able to tell me a few things when he went to get a coffee. He told me in that Tim Horton that I got the house and now he is changing his word. My son is a witness to it. He lied so I would not make a scene there as I was the one who brought up the kids he did not he did pay a single cent for baby sitting. what is he entitled to from the house. He want to controll the money there is mental physical and emotional abuse all along
