My heart aches whenver I think about the kids

Sometimes I think I am keeping this family for their sake. Sometimes I think I am such a bad mother for not protecting them from such unacceptable behavior. My older son is a nervous kid and gets angry easily. He's a teenager too but I think the abuse he has seen has impacted him greatly. My baby was born here and my hu*****and has learned to yell more than physically hurting me. So he has a good personality and he's like an angle to me.
