Should I tell him? Did I cheat?

My boyfriend and I broke up a couple months in the past. We’ve been having fights each and every 7 days and arguments by means of text nearly each and every working day. We’ve talked about the troubles. I told him how I felt about his drug use, and how it harm me observing him addicted to difficult medication (I don’t mind pot) and just supplying in way too significantly to peer pressure. Also, he seems to take pleasure in his time with his friends a lot more. I’ve told him numerous occasions. But nothing at all. He didn’t do everything. All he told me was to regard his choice on medication.
