My boyfriend is an alcoholic and I do not know how to help him.

My boyfriend, (29) has an issue with drinking. He works as a bartender for the past 4 years and ever since then he has been a heavy drinker, and tweeker. He also smokes weed, cigars and vapes. That is his life. I have been trying to help him by taking him to the gym, yoga, walks, hikes and other activities, but he always comes back to drinking. He used to drink more when he was in college, but not as bad as now. He used to be into Crossfit, but he quit, and he now says he feels too fat to go back and that people will judge him. I also tried to have him join my Crossfit gym, but he is still unsure. <br><br>Also, I want to add that he does not drink during the day, but he binges drinks once he is done with work and comes home. <br><br>I am starting to get worried about his health, especially after having a talk with my doctor. My doctor told me that he should join a rehab, but I do not know if he is ready. Also, I saw that there are few rehabs that are covered by his insurance, so I am stuck on what to do. <br><br>Any helpful advice? طت<br><br>Edit: I am also worried because he has been gaining weight and I am afraid that all the drinking will lead him to diabetes. Also, I feel like he is letting himself go and he has low self esteem.
