Husband lied to me about having kids, his past, everything

I'm absolutely heartbroken. I found out the day after Christmas that my husband is a liar and has lied to me about everything. I'm 36. My husband is 61. We met 5 yrs ago. We moved quickly. I think I was just scared because I was getting older and worried I wouldn't have children because of my age. We moved in with each other after 4 months of dating. Got married at 8 months and I was pregnant with twins within our first year of marriage. So we have beautiful twin boys. I was told he didn't have any kids. He was never married. Etc.

I now know he's a complete liar. He was married and actually had two children along with having gone to prison before. He only ever worked under the table jobs for our whole relationship and he always said it's because he doesn't want the government taking his money but I now know it's probably because of his record.

His ex wife's sister had reached out to one the day after Christmas to let me know the monster I had married and send me his criminal charges and old mug shot. He had abused his ex wife horribly. The sister said she was so depressed because of him she took her life. He also has TWO children. A 40 year old daughter and 26 year old son. He sexually abused his daughter. He impregnated her with his son and that truth never came out until he went on to sexually abuse his son when his son was 14. That's when the daughter came out and he went to prison for 2 years. I'm absolutely disgusted. I spoke to her and she sent me everything. My husband at first tried to tell me she was a crazy liar but when he found out I saw his convictions. He broke down and started crying saying he has made mistakes and the reason he did what he did is he was trying to feel the void after his wife died and he felt guilty for harming her. That he hasn't reoffended since prison. He lied to me. His two kids from me and his horrendous crimes.

I have taken the twins to stay a motel. I may be going into the new year in a broken marriage and my kids in a broken home. I'm devastated!
