Fiancé is attached to his bestfriend???

I’m so annoyed!!!

I’ve asked my fiancé in one hundred different ways to detach himself from his bff (which also rents a room at our house back home) (he got a divorce two years ago and needed somewhere to live) ANYWAY, We have a camping trip coming up and he keeps asking his friend if he’s joining us, and blah blah.. his friends girl and I don’t get along what so ever, and they’re both well aware of that! The last camping trip was not enjoyable bcus They come along when it was suppose to be a family thing.

This time around I took the initiative to text his friend and let him know how I feel about them being around so much, and how I need some boundaries. Well I heard my fiancé call him to ask for the 100X if he’s coming to the trip, his friend told him he wasn’t sure. I snapped, I’ve had enough.. i told him that I’m his partner, and how I’m tired that every trip we take they have to come with, that if he’s serious about our marriage that I need him to respect my wishes as I do his... There’s a family guy friend he isn’t okay with being around that I respected, and asked my family and the guy to respect my partner.. so why can’t he have the same respect towards me?? I love my fiancé so much but I don’t know how much more bestfriend I can handle.. When it’s just me and him we’re completely fine and never argue
