I'm a girl. Quite a few of my friends are guys: I'm a geek, so it just happened that the people I bonded with happened to mostly be guys. Some of those friends I've known since 7th grade.
Another important element: I'm single. No boyfriend at the moment. It's not that I don't want a boyfriend, I just haven't found the right guy yet.
My guy friends are getting married. Their wives are uncomfortable about the guys staying in touch. I can see the wives' POV: I don't have a boyfriend, and I'm there discussing with their husband that computer game (for example) that the wives don't understand. I share something with their husbands that they don't. Of course they see me as a threat.
How do I change that? How do I position myself as "not a threat"? The obvious answer is "get a boyfriend", and I'd love for that to happen, but until then?
Done so far:
I never ever invite only the guys to an activity - always the couple. However, it's usually only the guys who want a boardgames night, or a Star Wars marathon.
I am always supportive of my friends' relationships: "I'm so happy for you" etc.
What else can I do to make my friends' wives comfortable with the idea that I'm their husbands' friend?
