Adoption and trying to divorce

I don’t know where to begin but I’m trying to finalize an adoption and going through well. Haven’t started the process of a divorce. I haven’t listen to people about my husband as many red flags, but I’m still fairly young getting a used to marriage. We’ve been together for nine years going on 10years and married for seven and, how we got together. Yes, we cheated to get over who is with. I know it’s a long story. Everything was fine up until four years in to where I felt unappreciated not a partner no respect. Yes I should’ve left but me thinking that oh he’s going to change yeah change for a week then went right back to cheating, he cheats every year even though if it’s a text it’s probably twice he stepped out that I know of but this time around For the past year, he’s been cheating with a functional crackhead drunk. She has been known to sleep with married men. Ive told her to leave them alone, but they still found a way back with each other. No, he does not smoke it. I just recently caught them at the hotel room And he still there and we still are not done with Adoption. Yes, in those years I have caught an attitude I have done some things not cheating that I’m not proud of that. I shouldn’t let my anger get the best but since then I got into therapy and try to better myself, but then when he Nick picks my attitude comes and I become nonchalant but it’s driving me crazy Because I don’t know if starting the divorce would mess up the last bit of my son adoption. If anybody can give positive advice, it will be helpful. I am at a loss on which way to turn because he says oh you can stay at the house while I’m here with her at the room, but not understanding this house has memories so I feel the best thing to do is to move out and far away he wants to reverse it but I don’t want nothing with him no reverse no friends I hate that I have to coparent I am desperate, looking for help positive help I know this is long no one don’t want to read it it’s more but that’s just a few please help
