Hey everyone, my ex (father of my children) and I separated because I was no longer in love with him and he was becoming more angry and aggressive towards me in front of the kids.

He got into a car accident last year due to DUI and lost his car and license, so I would drive him places. When we separated I drove the kids to him, and drove him and the kids places (he lives on a boat with his dad, doesn’t have a house). I’m engaged now and my partner brought it to my attention that Im his ex and I shouldn’t be doing this much for him and that he is a father and should figure things out for himself to see the kids and me not have to drop everything Im doing to drive him around.

Recently when he found out I was engaged he started telling people that I cheated on him in the relationship with my now fiancé (not true) and is telling people Im this awful person. Ive been planning on taking him to court because we have no custody agreement. I have an audio recording of him saying “If you ever take me to court or put me on child support.. I will kill you, then your mother, and then myself”, also audio recordings of him screaming at me and breaking things in front of the kids.. is this enough to get me a restraining order? Will it prevent him from seeing the kids? I genuinely think he is mentally and emotionally unstable and I don’t trust him with the kids alone. Also Im pregnant now and I fear for when he finds out.
