So, my boyfriend and I have been together for three years, and he recently asked me to sell my horse to help him buy a new car. My horse is my absolute best friend and has been with me through thick and thin. I told him no, and now he's super pissed and says I’m not being supportive. He argues that a car is more practical and that I’m being selfish. I get that cars are useful, but my horse is like family to me. Am I really the asshole here for choosing my horse over his car?
