wife denies new truck purchase; need advice

[Dave92270]

OK, last night I told to my wife that I'm considering to buy (or maybe lease) an H2, new or preowned, I'm not decided yet; I want to keep my H3 as well, at least for now. She freaked out like never before and snapped back at me really bad that I don't need that etc... what is the next step when this happens? What arguments to use? She pisses out about $10k monthly in discretionary expenses yet won't allow a bit of fun for me? Need help. Need good arguments.

Thanks!!
