You should walk up to her and tear the tickets up in front of her face. You can always secretly reprint the tickets when you get home and go by yourself. She'll just think you are a man of principles and she'll gain a lot of respect for you. Don't worry, all that yelling and screaming and her calling you a "motherfucking dumbass" is just her way of showing respect.

Tell that bitch to shove it. Take someone worth a damn.

Take a buddy or a date she doesn't deserve that treat.

And that's when you ask her if you can still have sex just "as friends".

If you can't find anyone else to go with you, go on the cruise and have fun. Heck you may even meet a new GF on the cruise

Tickets are non refundable you say? Well this is what you do. You find some other girl that likes you and then take her with you. Then tell your ex oh I'm sorry but I found someone else to take. THE BIG PAYBACK

Why the **** would he want her back after that?

Sweetheart, you find a real friend and go on that trip with them. DO NOT TAKE that girl, she is only trying to use you. It is worth whatever it costs to change the name on her ticket. Then go have fun and celebrate your freedom!

Ask her Mom or Sister.

What a bitch!! Just count it as a loss and tell her that's cool. Then wait until she's all packed and ready and burn the ticket in front of her! haha
