I need advice please

So 2 weeks ago i found out that my husband has been in communication with a girl he has promised to stop talkinh to months be4 and i told her as well to stay away from my family. But they didnt stop talking to each other.Yes i am very hurt and upset but im 37weeks pregnant and he has apologize ans swore they are just friends and nothing happen even the girl said nothing has ever happend. So iv been trying to work it out for sake of my child but just on friday we got into an argument and i called him an asshole now hez been ignoring me since today textes that i should take responsibility for my actions and that the insult was unprovoked. He is milking me calling him an asshole like u wouldt believe im starting to feel like im the bad person and he expects me to grovel. Im still hurting from his betrayl and he has the nerve to be making me feel like shit. What should i do?
