When you say two weeks, I assume it's been two weeks since you've used. The first few weeks and months to be honest, that I was clean were an emotional rollercoaster ride. It's a recommendation that the first year in Recovery you don't make any big decisions. If your girlfriend is still talking to you after breaking up with you due to your drinking, I would consider you pretty darn lucky. I would suggest taking things slow. Just be her friend right now. I think you're going to find that things are very different between the two of you now that you're not drinking. You're going to discover new things about yourself as well.
Take things One Day at A Time and Congrats on two weeks!
God Bless,
Judy
