just need some advice related to boyfriend

My bf drinks a lot like 2 or 3 times a week. I met him at a bar so I got into the relationship knowing he was a drinker. but when is enough enough and should I leave. i love everything else about him and the only issues is he drinks a lot. he doesn't act angry or rude or any type of way when he drinks but it still bothers me. do I just let it not bother me or call it quits. he knows my issues and thinks I shouldn't ask him to change. which I agree kinda.
