Fighting with husband over a cruise

Me and my husband had an argument over over a cruise that his uncle purchased for us and never asked us if we would want to go or can go. I'm recently pregnant and have a 3yr old daughter. Am I a bad wife for not wanting to go bc I rather stay home with my daughter that's to long for me to be away from her. So he is mad at me now. And I'm very upset of it bc I feel my family is only good enough ever to be a babysitter. When I have family functions he don't attend them but I attend his. Also my family is our babysitter and keeps a rough over our head until we move out. Am I in the wrong?
