What Do I Do? Help!

[labug]

I have to figure out what I need to do show her or prove to her that I'm done being the way that I was.

If you are doing this to prove to her you've changed, you may fail. The key is looking at your behaviors, accepting that they are not healthy and then changing them so you become a better person in all your relationships. If you really change, she will notice over time but it won't happen overnight.
