I’m a pharmacist, she’s a nurse.

I (38M) date a (35F) nurse. She works at the same hospital I currently run the pharmacy at. She’s been a handful from day one. After some time dating I realized she was hooked on painkillers. She would always tell me how her back was hurting to how she’d worked a double shift and was wore out. She always seemed to need some relief and I chalked it up to her demanding job and tough schedule. I also lost my job over her drug abuse. Shes my everything though. After about a year into our relationship I found out she was married and also had 2 young children. I didn’t want to but I immediately ended the relationship. The real kicker here is she’s been working at the ER and still uses drugs heavily. I’ve since come to terms with her using me to supply her habit and I do take responsibility for that.

Recently she reached out asking for help getting clean. I wanna just block her and walk away but we have some mutual friends and I don’t wanna come off as cold. AITAO if I block her and not help her get sober?
