My bf and weed

My boyfriend smokes weed sm we kinda have a long distance relationship as he goes to a boarding school near my boarding school but in summer I rarely see him but hes out everyday and gets High almost everyday and it just gets on my nerves sometimes as I really want him to have fun and spend time with his friends but the weed is abit excessive and I personally don’t like getting stoned but idm that he does it it’s just a lot on we don’t talk much as he’s out all the time but I don’t know what to do as I respect that he is out with his friends having fun so I don’t know if it’s fair for me to say something
