I know personally that dealing with someone with a drug addiction is difficult. I also know personally of a few women that stay with their drug addicted partner. I’m still trying to understand this myself. This reasoning. This rationale. Everyone thinks differently & follows their own philosophies in life. And those can change too.
Everything can change. Hopefully you will find the answers you’re looking for. Inside yourself.
Best of luck & no matter what you decide, stay or go, I’ll listen & try not to judge.
