I'm upset with my wife for wanting to cut our vacation short
Why does your wife want to cut your vacation short?
She always wants to leave early and go back home.
I get you're upset, but you should try and understand her reasonings for wanting to cut it short. Otherwise this may just lead to a big fight.
I don't care about her reasons, I'm tired of always doing what she wants.
You should talk to your wife about your vacation plans and make plans the both of you can agree on and follow. It will allow both of you to enjoy your trip more if you're in agreement about your plans.
