Dont trust

I dont trust my husband with are son. When he watches him he yells at him. Hes only 5 months old. Hes teething he cry. Im scared. My husband might shake him. I grow up in a bad situation. Am i wrong wanting to leave, couse i do t trust him. He dont talk to me or anything anymore. Its like he lost interest after having r son.

Anyone with advice?
