She couldn't handle me being sober so she left.
Then she was back under some new 'just dating' BS.
Gone again...then back...
Holidays with kids were a mess.
More holidays are coming!
Didn't drink yesterday or today and have no plan to drink tomorrow.
It's a test right? I can't fail this one!!!
F c k her.
Sobriety is more critical than romance and companionship.; sounds like she puts yours in detriment. Stay sober and ignore her as much as possible to win this "test"
Good luck man.
Keep your head up, this is for you and your future. 
Getting sober will make some people in your life uncomfortable. They will be threatened by your growth. They will either encourage and grow with you or fall to the wayside and that’s ok. Sick attracts sick, healthy attracts healthy. You’ll find someone that’s fits into your new life.
