Can I just vent? Ex-Husband

So, I was married to a man for about two and a half years. I knew he had an alcohol problem before we got married, but didn't realize how serious it was until we got married and he began doing certain things: lock me in our bedroom while he was drunk and we were arguing... didn't come to the hospital after I totalled my car, while I was pregnant, because he was passed out drunk.... Verbally abusive, threatening to knock my teeth down my throat, would take my car and leave in the middle of the night for hours, never cared to create a bond with his daughter, though he sure was good at pretending.

He was terrible and the final straw was that I found out he was doing pills, because he was stealing my dad's. I kicked him out, and he began dating before I even filed for divorce. He took my daughter out of state with his girlfriend, and turned off his phone. I panicked because I didn't even know she was out of state. Afterwards, I spoke to an officer and they told me since we were still married, it wasn't illegal. Anyway, he decided to move to where all of his family lives, in northern Tennessee, about nine and a half hours away. I was relieved, because I wouldn't have to be afraid anymore. But, we have a beautiful baby girl together. He chose to leave her, but is all on Facebook talking about how much he loves her, and is posting pictures as if she is with him there. I began dating this guy, who my daughter loves, and he treats her so well. My ex husband called saying that he would he best up my boyfriend, and he better not be playing daddy with his daughter. My ex has yet to pay child support.. even took my wedding rings and pawned them for child support money. I still am doing this all alone, with no help from him. He called my mom and told her he won't call my phone, so now he's cutting even more communication from Ammarie, because its not like I'm with my mom all the time. The day after he moved, he got a job offer at the air Force Base that he's been trying to get on for several years, they wanted to interview him and he turned it down. He is up there living with his dad, no job, no car. I'm angry that he has chosen over and over to not step up to the plate, and be what she needs. But, Ammarie will know who loves her, and who is in her life. I just wish he would give up his rights so that there is nothing he can do to hurt her in the future. But, that's selfish of me to even think like that. I just hate the idea of him showing up in her life whenever he feels like it. If something were to happen to her, he would have just as much say as me, even though he's not here to love and take care of her. I don't see how you can look at your baby and not want to be better for them.
