Been seeing this girl for 4 months, and we're in a relationship. She has 1 long term male friend from her hometown she's told me a bit about.

They don't meet very often, and have been planning on getting together for a while. He is now coming over and staying at her place over the weekend.

This was all set in motion before we were in a relationship and i never really had a chance to do anyhing about it, and she is now very excited that I'm meeting her "long term friend". She also made sure im aware that he's sleeping on the couch.

I'm not quite sure what to make of this, on one hand he seems like a beta orbiter and that I shouldn't worry. On the other I really don't like random dudes spending the weekend at her place.

So far she's done everything to please me and would probably have a breakdown if she thought she did something i didnt like. I'm pretty sure she just doesn't realize that this might be crossing a boundary.

What is the best approach to this, please share your opinion.
