Their dad wants to apologize

Me and my husband recently separated. I came here looking for advice on how to handle my husband being jealous of our two son's. He hated when I showed them affection and woild get mad and say what about him. They're 14 and one is about to be 17. He would get mad if I showed them love. He became very verbally abusive towards them and got mad when he asked if I had to save them would I choose to save his life and I said no I'm shaving my kids lives. He never acted that way towards our daughter and some people suggested that maybe he is sexually abusing my daughter which isn't something that happened. He did accuse me of wanting to have sex with my two sons. Really weird shit. Someone left a weird comment on that post saying that this is normal because men are like animals and it's in their instincts to get jealous when we show another male figure attention and told me i needed to stop acting like hes jealous of his sons because it's how men are wired. I asked every man in my life who has or had teenage sons. My dad, my brother, my brother in law. All of them said that's not normal and they never felt that way. I did attempt to try to save. The marriage by suggest counseling. That went out the window the day my husband made the decision to angry drink before picking them up from school. They had some type of fight in the car and my 14 year old said "I fucking hate you" so he started driving crazy and pulled over and proceeded to BEAT on him and 16 year old had to fight his dad to get him to stop. Because of that we are under investigation from fucking CPS. And my husband got a DUI. Public intoxication, child endangerment and child abuse charges. We sre currently under investigation by CPS and my husband is no longer allowed in the house. He did reach out to apologize to me and says he was just jealous and blah blah blah. He said if it makes me feel better he would apologize to the boys. The boys do not want his apology. I don't know if the apology would better or worsen the CPS case anyway. Our marriage is over. He's tried but I'm filing next week. However I do think he owes them an apology even if they won't hear it.
