I don't know what to do anymore. Every time my husband is upset he seems to threaten that he's going to kill himself. Today we had a small argument in a store and I ignored him when we got home because I was upset. Well like usual he lost it. Started screaming at me in front of our 7 month old, swearing at me. It ended with him grabbing his keys, declaring that he was going to kill himself and driving off. This has happened dozens of times before and now that I have a child I don't know what I should do? I don't want him growing up seeing this or thinking it's ok that his dad talks to me like that. I also don't know when it's serious and he needs help or when it's just angry and I should give him space. Thoughts?
