I (22 m) made a friend (19 F) a couple months ago and me and her have gotten pretty close to each other. In the past couple weeks though I discovered she’s into drinking and marijuana. I’m not into either of those and I personally can’t be friends with someone who is. I told her my opinion on the subject and she said that she would stop if it means losing me. I obviously like that she wants to stop but drinking and marijuana are things that she enjoys. She’s upset that her friends and family are doing it and she can’t. I don’t want to lose her friendship but also can’t be friends with someone who’s into that. At the end of the day I feel like I’m being controlling and manipulative for holding her back. How should I handle this?
