Husband constantly thinking I am going to leave

My husband and I have been together for 2 and a half years. None of these problems came out while dating. It first showed its face during our honeymoon 10 months ago. Anyways his parents verbally abused him. Called him stupid, not good enough etc. He says this is why he has these problems. Well about every 3 days he’ll get into this has these episodes where you can’t tell him anything. He is just constantly thinking I am going to leave him (we have a newborn together). He’ll say “do you love me” “are you going to leave me” and I’ll tell him no!! I reassure him all the time all day long everyday. We text all day long.. I am a stay at home mom and do nothing. I am at his beck and call. If I put on make up he thinks I’m going to leave. Today our son had a doctor appt and I put on the tiniest bit of makeup because I felt insecure in my glasses and had no more contacts. Well he came home from lunch and saw that the makeup was out and asked if I put it on and I said yes a little because I felt insecure in my glasses. I told him it’s really hard for me to hear him down on himself and in these moods all the time. It’s frustrating for me because I’m literally doing everything I possibly can for him and our baby. I told him that this is pushing me away a little and he said “so you’re going to leave me? I should just kill myself”. He is seeing a counseling and going to adult children meetings and talking to people. The problem doesn’t seem to get any better😖 any advice? Maybe marriage counseling? It’s taking a toll on me mentally and physically. I am constantly thinking “will he be mad if I wear this? Say this? Look this way? Does he think I am looking at someone if I look at that outfit?”
