The test is will you chase her when she treats you bad - CB. Never chase a bad cat. If you need to apologize for your behavior that is different.
If she walks out when you are talking then you need to talk about the behavior.
Griping is good, make sure you get to the real issue. Something is on her mind that she needs to talk about. One of my favorite responses is, "how can I help you with that?
Pursue real issues not bad behavior. Then she will really want you "come after her."
