As to question 1) Yes. I have really only been in love once and I left that man because he was holding me back from diving headlong into drinking and drugging. He loved me unconditionally yet I pushed him away.
2) Since you choose AA as your recovery program I would strongly suggest you stay very close to your sponsor and the people in the rooms. If you can't do this for you then just do it anyway. Do not drink and allow yourself the gift of being sober.
I quit years ago for my kids. 13 years without a drink.
Best to you.
