Is it wrong that I don't want my boyfriend to drink?
Why don't you want him to drink?
I've tried to talk to him about this problem but he refuses to listen
If you are concerned it's a good thing. If they can't control their drinking they do need some help.
Having my boyfriend not drink is like throwing a ticking time bomb into the air! I can't tell him what to do!
Your boyfriend will make his own choices in life, but you can point out issues that you think he should work on. Then you have to step back and give him time to make the right choices for himself.
