Ditching Party - 2010 was released on:

USA: 2010

No, she's happy so she's not ditching him.

The proper grammar would be: "I am mad at you for ditching your brother and me." "Me and your brother" works just as well. When in doubt, just take everything out except the personal reference. You probably would not say "I am mad at you for ditching I." or even worse: "Me am mad at you for ditching I." I is used as a subject, me is used as an object. The usage "I am mad at you for ditching your brother and I" is a very common error made by people who are perhaps trying a little too hard to be formal and correct.

You should ask him the reason for ditching. If you have done something bad, apologize for that.

Running out on them.
