should i fight my sister she was making out with my bf (boy friend)?

Answer 1

You have every right to be upset, that was wrong on both of their parts. Personally I would break up with your bf, if he can cheat on you with you own sister he can cheat with anyone.

You can't break up with your sister, so you need to sit down and talk to her, get it all off of your chest so you can feel better. I am so sorry that you were betrayed, I hope you figure it out.

Answer 2

Not really.You must talk to her and your boy friend about the matter.Something is wrong with that picture and you must be clear with the two.Just in case.You never know.... open your eyes....
