No, too much aggravation and drama.
No, but there are two related factors that might make it seem that way. first, I'll often relax and be more open with a girl when she's in a relationship because I don't have to worry about sending the wrong message. Second, a girl might relax and be more friendly/flirty when she gets into a relationship for exactly the same reason- plus the self confidence boost of being in a new relationship. So a girl who is in a new relationship might often be more attractive than she was before, whether or not I know it, and the fact that I know she is in a new relationship might change my behavior in such a way that might lead her/others to believe that I find her more attractive.
Well thought out
Not at all
Don't even think about playing the game.
