Today is D Day. Divorce is final

Not sure how I feel as I wake up this morning? A little lost. A little sad. What are the next steps? My ex and I still live together. He’s pretending like nothing is different. Weve been together for 10 years and he pushed for a divorce after he found out I had a male friend I was getting to close with. I was lonely. And he’s never been the man I’ve wanted. He’s lazy, sit around and plays video games and ignores me. I needed a partner. So after he found out, he pushed for a divorce, we’re stuck living together bc neither one of us can afford to live alone. And for the sake of our children. How can he act like everything is fine?! Still tell me he loves me? I feel for the first time since I was 18, a complete sense of loss and failure. Should I move on with my life? Or should I just keep on keeping on? I’m so sad.
