There are gazillions of guys out there. I firmly believe that friends should never ever share boyfriends. In fact, last year, a friend of mine moved in with my highschool boyfriend. I was pissed. She thought that was ridiculous because I am married and I was with that guy 10 years ago. But it didn't have anything to do with me being jealous or whatever. I just think friends shouldn't do that. There is no reason to. All of my friends know that I feel very strongly about that subject. I would never ever touch any guy they dated and I expect the same respect. So, to sum it up...your friend is wrong.
