My husband and I are separating

I know a lot of people on here and in my real life wanted me and my husband to break up. We have been in marriage counseling a year. We get into very verbally abusive and physically fights. He's pulled my hair out, I've broken his nose. We are both very abusive. My son is 13 with a boyfriend he just hit 2 years with. Their whole relationship started off as a bet. They used to hate each other and now they truly care for each other. They actually broke up last week over something and my son was hurt about it for a while. I told him they were young and it was bound to happen and his boyfriend came knocking on the door. They talked outside and me and my husband listened a little and the gist is his boyfriend said they aren't perfect but he does love him and he wants to work at their relationship. Everyone always joked and said my son has a healthier relationship than me and my husband and me and my husband both truly saw that through those 2 in that moment. My son has really bad anxiety but his boyfriend always seems to know how to calm him down. They support each other and I shouldn't be looking down at their relationship compared to the examples me and his father gave him. I think when we saw we wanted a relationship like our barely teenage son we knew. It was time to split. I moved out yesterday and it was weird.... I had tears but at the same time felt..... Relieved... Me and my husband are going to do split custody. I owe a lot of people apologies. My son being one. I apologized to him for downplaying their relationship. At this point whether or not they do truly stay together doesn't matter. What does matter is my child knew at the age of 11-13+ how to have a healthy relationship with communication. And another thing I'm trying to relax a little more on is that their relationship isn't as pure and innocent as I wanted. I found out they have had their first kiss and they've been together two years. Even if it wasn't serious for me it is for them. IDK what happens next in my life but my own child taught me what a healthy relationship looks likes. I'm not worried about a relationship right now but at least I know what I want from a partner and always plan on working on my own toxic abusive traits.
