Boyfriend goes to the bar every night

I would like advice and how to deal with this situation without seeming super controlling, or what I can say specifically to make my boyfriend understand that his behavior is affecting me. Im F 36 he is M 35, I met him online and we have been dating for almost 4 months now. He has a good paying job and treats me like a queen, always taking me out on dates and being super thoughtful and caring, and with the way things are going (other than this problem) I could see myself marrying him, kids and all the rest. My problem is that he is a bar fly. He has a bar close to his house within walking distance (I live 30 mins away and tend to always head to his direction if we hang out, he does offer to come my way too but I prefer going to him) and he is always there! Any friends he knows, he met in the bar and has been going to this bar since his 20s. Any free time that he has he is there, spending all of his money, and is always buying drinks for other people and makes me upset that he spends so much time and money there. I think my biggest problem is that I've asked him to let me know when he gets home safe, the nights im not with him. And much of the time I cant sleep wondering where he is/how he is and it disrupts my sleep. I would say he only tells me when he gets home once in a while, because he doesnt want me to know how long he is actually there. One time he is was there for 8 hours.... What can I say specifically to make him understand this effects me. Would you tolerate this in a relationship? If we get a house I want to move far away from this bar but I wonder if he would through a sort of depression because he wouldn't know what to do with himself.
