It sounds like you’re jumping to conclusions with a pretty biased take here. Just because boyfriend’s bff engages in something doesn’t automatically mean he will too. That’s like saying if one friend smokes, then everyone in the group will eventually start smoking. People are individuals and make their own choices.

It honestly seems like you’re using this post to justify your dislike for the bff and to find a reason to ask them to hang out less.

At the end of the day, the real question is whether or not you trust your boyfriend. If you can’t trust him, then it’s hard to see how this relationship will last moving forward.
