Maverack, dude, I think you need to calm down a little.
She's been your GF for 2 years and he's been your friend for 10 years. If you're really close with both, doesn't it make sense that they would become friends? And when guys and girls are friends, things can get slightly flirty compared to two male friends. I wouldnt worry about it.
Are they really that flirtatious?
I don't know man, I'm good friends with my best friends girlfriend and there has never been any problem. We all hang out, and I'm sure it's not uncommon for her to bring up some funny stuff I did to my best friend. Hell I've slept over at her place, and her at mine, in the same room, and it's never been an issue.
Do you trust these people or not? Thats what this comes down too. You've known them for a very very long time, so I hope you do.
