am i wrong for getting mad 😡

Long story short my fiance bought me a truck right im a stay at home mom. He has a tahoe he decided to put the tahoe in to the shop to get painted and new upholstery without consulting me so now he uses "my truck" and leaves me home with no transportation for anything now i have to make the kids appointment around his schedule i understand he works and all and i appreciate that but than he goes out to buy a truck he wanted and never consulted me about it he wont use that truck for work its just for weekends and i know hes not gonna use the tahoe for work since he's a landscaper he needs the bed of the truck, am i wrong for feeling some type of way instead of buying me a little dependable car he buys himself another truck hes just gonna use on the weekends and its single cab and we have 2 kids 😒😒 so now my mom mom is helping me buy a little dependable suv my fiancé should do that instead of my mom but he gets mad everytime i say something because he says i work
