Hi all, My boyfriend is an amazing captain and in general our relationship is pretty amazing. However my boyfriend was recently given meth by his loser father (I don't say this to my boyfriend, but like his dad has not had a job in two years, is divorced from boyfriend's mum for beating her and generally being a bad person). My boyfriend still has a 'fairly' close relationship with his dad (feels sorry for him, as the man's lonely) and so visits his dad about once a week or fortnight. Two weeks ago my boyfriend smoked meth with his father for the first time and now thinks it isn't a huge deal, and admitted that he will probably do it again and that it's 'kind of fun' and brings him closer to his father. This really bothers me, and I don't know how to raise the issue without causing my boyfriend to believe I am accusing him. How would I raise this issue to my boyfriend in a way that will allow him to not brush off my concerns or to believe I am personally attacking him.

Thank you

*Edit: thank you all for really pushing how serious the issue is. I am going to raise the issue with him asap and be prepared to leave if he doesnt respond.

I just didnt want to face the music , i really love him a lot.
