Wow, trying to trick a guy into dumping her is way, way worse than getting a reputation for ending relationships that aren't working out.
If a girl dumps a lot of guys, it basically means she has a hard time of reading how a person will behave until she is already in the relationship. If a girl starts doing negative actions to sabotage a relationship she wants out of just to try and save face by having the guy dump her first, then she looks immature and manipulative and would send up so many red flags I would feel like I was part of the running of the bulls or something.
My thoughts would be to tell her to just do the right thing and break up with him.
