Is it normal to help the person who left you?
Lets say there was a girl and she tried to make all the guys chase her. There was 3 in particular she was after and decided to try for one of them if not all of them. Only one perused her though and that was you however she would not make a commitment since she was holding out for one of the other two.
One of the other two is the pursuers best friend. Who in the end they realize the Best-friend was willing to give the girl up for him. So eventually the pursuer gets impatient and gives up the girl telling her go with his best friend who ironically had the same exact intentions.
She ends up with the best friend since the pursuer gave BF the green light. However now she is jealous of a female friend Best friend already had since she is still hanging all over him. Would it make sense for the pursuer to still help this female after all this? Just out of sympathy as she now tells the pursuer about all the issues she has with the best friend. Yet the pursuer really wants to see his best friend happy with this girl and knows he likes her a lot.
