I think I'm my wife's bad guy.
That sounds horrible. How do you know she thinks your a bad guy?
My wife told me she she sees me as a bad guy.
If your wife tells you that you're a bad guy, then there's a good chance you are treating her rudely. You need to take a hard look at your actions and how you behave and change. Talk to her about what you do that she dislikes so you can improve the relationship.
I'm a bad guy, why should I listen to her.
Because do you really want this for your marriage, where one of you thinks the other is a bad guy. You should think of your actions and if you are being rude to your partner, you should be better.
