I want to go to Disney and leave my pregnant wife and one year old behind
What makes you think you can go to Disney and leave your pregnant wife behind?
Don't you realize how much of a hassle it is to take a family along with a kid and pregnant wife? It makes me cringe to think about it.
You should not visit Disneyland without your family. You should want to bring them along with you so you can all enjoy it together.
I should do what I want!
You can do what you want, but your wife will be very disappointed if you go without her. She will think you see her as a burden and it could cause strife.
