Tyler,

Great if she wants to go out use it as a starting point to show the new you, I would not bring up all the other things I mentioned unless you feel its needed, that was to try and get your foot back in the door.

It is more important to show her than tell her anyway. I would still apologize sometime in the future but its always better to build some good will (over time) before jumping in if you can, so save it for another day.

Just be the guy you feel you should have been, and try to relax. Take it slow and easy time will heal especially if you show that you have actually changed. Just make sure you are happy with the changes you are making, because you will always have to look yourself in the mirror.

Good luck
