Husband hid all this from me

My husband and I got married back in November and I found out he's been hiding a lot from me about his past. I know he's been to prison. I have also been to prison back when I was on drugs. He told me he went to prison for drug trafficking and I didn't judge because like I said I've also been to prison. He works at a warehouse and makes good money and I'm currently working full time and in college. Well I just found out he's been getting money from his parents and they are now cutting him off completely. His parents have been paying his bills. That's because his wages have been getting garnished. The reason being that he didn't just go to prison for drug trafficking. He unalived an 18 year old. He accidentally hit him with his car while because he was speeding with a car full of drugs and just pushed his body into a bush and fled the scene. I'm surprised he only served 6 years for all that. But anyway the family sued him for wrongful death and he owes them over 3 million dollars. And he hid ALL OF THIS from me. He said he knew I wouldn't want to be with him if I knew everything. I have two kids. I have split custody with my ex but yeah I wouldn't have taken on all this burden. I have only had my 50/50 custody back for a year. Yes I've also been to prison but I haven't killed someone! The fact that he didn't tell me this. I don't know if I want to continue this marriage and we JUST got married.
