Leaving my abusive, Bipolar husband

It would take way too long to give the whole story so here’s a bit of a summary. 5 years ago I met my husband and he immediately manipulated me with emotional abuse. I was young and I didn’t know any better at the time. We got pregnant 3 months into a very toxic relationship and I told myself things would get better. 5 years and 2 kids later, years of verbal, emotional and physical abuse. Raising our daughters on my own and providing for us financially. I feel so dumb for rationalizing staying with this guy and continuing to feel as though I needed to take care of him. I was essentially his mom. Only after I left him did he seek help for his mental health and he was diagnosed bipolar. Now he wants me to give him a second chance because he claims he doesn’t remember ever hurting me and because he’s bipolar so it really wasn’t him, or so he claims. I’m still in the middle of this and the drama but getting away has shown me just how awful it really was. And sharing what happened to me with my family and friends made me realize all the things I rationalized were ABUSE. Please please please, if you feel as though you’re in an abusive relationship, get help, get out.
