Finding out u married a moron

My SO other is a piece of shit..I'm pregnant with our second and just realizing this. He is selfish and arrogant. Calling me worthless..telling me he hopes the child comes out with African American traits so that he doesn't have to care for it..seeing as I'm white and marries idk how the f he expects that to happen but OK. I don't even have a female friend...let alone a male. Ugh. Makes me sick
