My husband left me at the hospital

We got engaged , then married. We got pregnant on purpose & unfortunately lost our baby girl to preterm labour loss. I birthed her & he was with me the whole time & was so supportive. Month after got my gallbladder removed also. By a month later we were pregnant again , fast fwd to March 30, I go into preterm labour (loss) again & as I’m birthing my boy. A second boy pops out. We lost twins :( except this time he wasn’t there for me. He wasn’t sweet or supportive. I lost so much blood I almost died. Had to have a D&C right away. 6 bags of blood. & he just wasn’t being supportive emotionally for all I was experiencing. I could feel him off and he only wanted to stay the first night cuz of work so I said, you can leave now if you want. And he did. I haven’t seen him since. He hasn’t asked how I’m doing. Doesn’t talk about our babies urns being made. He didn’t even check up on my two older sons who were at home while I was in the hospital. He just. Vanished and ghosted us all. Next day he asked for a divorce. Now he’s making it like I was a terrible wife and no one would want to be married to me. Like I’m a liar about my entire past and everything that ever happened between us. He only text he’d never call. And then Saturday he came to get his deer meat and leave the house key. Didn’t leave his wedding ring which is something he’d do. Didn’t even take his personal items or his hats which he loves. I just don’t get it. Now we’re no contact and. I don’t know what to feel or what to do. I’m So lost. And heartbroken.
