One thing I really have to work on is simply validating. When she starts in with how much she doesn't believe me, or my changes aren't real/permanent, I have been making the mistake of trying to point out where I have changed, how far we have come and how things are improving.
When I defend myself it just leads to a conversation about past things, how we have been trying and its just not working, how she has tried before but we keep coming back to the same point. These conversations wouldn't happen if I would just let her say what she has to say and not respond.
Is there ever a time where its safe to respond or does the need to even address the "you're not really changed, I know you" issue just go away with time?
