I hate this crap

ok my girl dumps me right, asks a guy to prom 3 days later because "we would never get back together", and then wants to get back together. There is no way she will end the date with this guy. She wants to be my girlfriend too. she claims this guy is just her friend.(have her cake and eat it too)

Everyone says she is not worth it. I am so infatuated with her. but she treats me like ****. This being an example.

should I

1. Play her ass and use her devilish ways against her

2. Walk and get one of the many other chicks who want me

3. Succumb like a little b!tch
