I recently discovered my dad (who is now in his 90s) was secretly a life-long alcoholic. My mum kept this secret from me and my siblings. I feel like things are starting to make sense and unravel at the same time. I realize I've often had relationships with men with substance abuse issues, normally I haven't noticed until I've got attached and it makes so much sense now because my biggest male role model demonstrated all the behaviors of an addict without me knowing that's what he was. So on to my partner who I've been with since 2018. He uses cannabis. He tends to vape cannabis on his own after I've gone to sleep at night. If I get up before he goes to bed his office often smells like weed. I've asked him again and again to let me know when he's using because I need to know if I can rely on him for support with our (3yo) child overnight or not. He's convinced that he's not using too much, he likens his cannabis use to someone having a small glass of wine in the evening from time to time. I don't use cannabis, so I have no frame of reference to know whether he's being realistic with himself. What I do know is he's very avoidant when it comes to discussing relationship issues and he's not fully capable of ordinary adult life, like he wears clothes with big holes in because he can't get his head around buying his own clothing, and he doesn't maintain consistent contact with his friends or family (they tend to check in with me to make sure he's alive). I feel overwhelmed with work and childcare most of the time and I think if he cut down his cannabis use it would take the pressure off me, but he just doesn't see it that way and gets defensive when I raise it. I don't feel like there's much advice out there for people in relationships with cannabis users. It's different from alcoholism. Does anyone have any words of wisdom for me on managing life with a cannabis using partner?
