I am starting to think this is a troll thread.
However, if not, your friend is... not secure. He's anxious and worried about what his wife will say and do to him. Part of that is likely due to his past relationships with women/how they made him feel about himself, and the other part is his woman taking advantage of his demeanor.
He is caught in a trap, and can't walk out, because he loves her too much + the baby. She can't see, what she's doing to he, and she don't believe a word he says while he's out, that's her past/upbringing coming in to play.
They can't go on together, with suspicious minds. They can't build their dreams, with suspicious minds.
