Narcissistic husband

How do you deal with a husband who’s narcissistic? He’s never wrong, he will torment you and verbally abuse you till you finally leave then blames you for leaving after he’s told me several times to leave his house and take my kids with me. We left of course it’s been 3 weeks, he pretends to care by searching around asking my parents, not me, but my parents where I was. Has yet to reach out to me just to tell me “you left now deal with the consequences” I have a 2 month old now we left went he was a month old. Hes angry because When I left I didn’t tell him I was leaving. I have anxiety at night I can’t sleep.
