Irritating situation

Cate

My SO is into RC cars with his friends at the moment and has 4 RC cars. He recently bought a $400 one and already is saying he’s going to purchase an $800 one. It really bothers me bc I feel like that’s such a waste of money when we could use it for other things. I’ve told him how much I think it’s a waste but he doesn’t care. I don’t even know what to tel him anymore. He’s set and stone about getting the $800 one.
