She holds things against you,never let the past go,always remind you of something negative in our marriage

Welcome to be married to a female. All women don't do this, but most do. Some men are just as bad or worse.

What sort of things does she hold against you? Are they big things that you two haven't resolved? Have you sat down with her to try and resolve them?

Also, how long have you been married, and how old are you both?
