Alot depends on if you're staying friends or not. Personally, I don't see any reason to give gifts to each other, especially since he CHEATED on you!

I wouldn't want ANYTHING to do with the creep. I'd take the gifts back to the store, and get my money back.
He does NOT deserve any gift of ANY KIND -- he deserves a hammer upside the head in my opinion.

And why give his parents any gifts -- they brought up this moron. Obviously they didn't instill him with any morals.
Get your money back sweetie. Don't waste it on anyone like that. God bless and take care.
