I think my behavior got to be intollerable. I can see that now. I think her problem now is that she can't let go of the past. Not just with me but a lot of things. The other problem is that she does not trust my changes yet. She is still waiting for me to go back to what I was like before.
Yes to all of this. That is why it is imperative that you do 180s. If you used to get extremely upset about something... let it roll off your back the next time. This is why it's so important for you to stay positive yet not overbearing. Attractive is feeling good and being happy.
Elaborate on this self-described "intolerable" behavior...
