I'm going to break up with my boyfriend over a Christmas gift he gave me.
That seems petty. What does he usually give you?
He buys me presents and we go out for a dinner
Gifts should be appreciated, regardless what they are. It's okay to be disappointed in a gift, but breaking up with someone over one is pretty shallow. Maybe you should consider giving him a list of what you might be interested in next time.
Well, it's because not one on this Earth can ever satisfy me.
It sounds like you need to tone down your expectations from others. You and they will be happier if you don't expect things that you know they can't give you.
