I'll try to talk to my husband first to see if we can fix the problem (seeing a counselor, etc) and support him through this difficult task. I'll let him know din the consequences of not being able to manage the problem. If he really isn't able to fix it, then at least I told him in advance what would happen.
We will try to resolve first his anger management problem including seeking professional help. I want to try first all possible solution before resolving to separation. Aside from that, I will also consider how it affects our children like if he is hurting them physically whenever he is mad.
