He isn’t helping out
You bring him to your parent’s house for dinner, he never offers to help. He is watching TV while you’re preparing appetizers. He’s still on the sofa when you’re washing dishes. Tell him that it is embarrassing for you to have your parents see this—that it says to them that he cares little about making your life easier — not only at this dinner, but at all times. Is that what he wants? You know you don’t.
