Well done! Enjoy the rest. She may or may not want to join you, but may I suggest she not. It is distracting. This is why I suggest no "hanging in", doing little supports and being their only when SHE needed.
A's have more support than they can handle if they want. They have rehab, counselors, sponsors, therapist, government agencies, AA/NA meetings and friends who will become their new family to your exclusion. These little contacts and help on standby are like little shots of a drug for codependent people. When the As is around, you will instinctively stop focusing on yourself and focus on her even if it just for lunch, the conversation will be about her, her sobriety, her program, her progress etc. etc. She being an A is still self absorbed and will let you focus on her not even noticing that you are burned out. Give yourself a real holiday dear.(((hugs)))
