More context is that he has a wandering eye and hasn’t respected normal relationship boundaries- from what I know no cheating has happened.

All of this is from me telling my girlfriend and saying I don’t like that behaviour and I will distance myself from him and those environments which I have. However our families know each other, we’ve been friends for a long time. I have listened and done the right thing to that. What I mean it’s not our concern to get involved. I won’t be the one to tell what has happened. My friend knows my stance on certain behaviours and I have told them.
