Would you mind if the person you are dating is dating someone else who is the opposite gender you are?

So there was the question earlier that asked if you would stay with your significant other even if they were bi.

BUT my question is would you date someone who is Bi, knowing they are dating one other person, and that other person is the ‘opposite’ gender of you?

(i am premising this on the fact that no body has chosen to be exclusive, so any of the people in this scenario can date other people if they want).

So you are a man dating a women who is bi, she is dating a girl at the same time

OR
you are a women dating a woman who is bi, she is dating a man at the same time

OR you are a woman dating a man who is bi, and he is dating a boy
OR
you are a man dating a man who is dating a women also!
(i think i covered all the simply bases—geeze! haha)

Would you continue dating/ feeling comfortable dating this person (assuming you like them) if they are playing the field for the other team???
