Losing myself

My husband and I are on the verge of divorce, he mentally is so abusive... we’ve been together 3 years and he was no where who is today... I came into the relationship with two daughters from my previous marriage. Things were picture perfect at the beginning and then we got married, and things have took a downward spiral, I got pregnant with our son and they really started going down fast... my son is a year old and he refuses to let me work full time in the career path I took... he says the time away will really ruin our marriage... today he told me nobody would ever want me with my three kids because I wasn’t worth it. That he’d have so much more without me and I wouldn’t have anything. I’m losing myself.... I’ve never felt the way I’ve felt.... I just needed to vent!
