I have a very close male friend that I work with. He has been in a relationship since before I met him. Around the time we started working together, we also started working another very close friend of both ours (who is female). At the time, I was aware that male friend's DP was quite jealous of her and felt that her and male friend were flirtatious as they got on very well very quickly. This was a few years ago now and I'm pretty sure she doesn't feel that way any more, in large part because female friend is so different from male friend in a lot of ways and also she's had a few relationships.
Last night, the three of us went out and it came up in conversation that male friend's DP finds me 'threatening' as she thinks me and male friend spend a lot of time together. We do, that's true, but this is mostly because we work together and because neither of us really have that many friends.
Though I still don't know the DP that well (it seems now male friend may have been intentionally keeping us apart to keep from upsetting her), I always try to be friendly to her, especially since she's now working for the same company (though in a very different area so we don't see her often). For the record - there is absolutely nothing romantic between us, never has been and never will be, plus male friend is very, very committed to his DP and completely despises cheating. She has absolutely nothing to worry about with any woman, let alone me. AIBU to be a bit upset by this? I know a lot of women on MN don't like their DPs being close friends with women but he's basically only friends with women, I had no idea she had a problem with it.
Sorry if this is a bit long and not especially interesting 😂
