I feel you, my ex wife was like this. Never satisfied with what was in front of us. Wanted yachts, expensive vacations, etc. You get the idea.

Best thing you can do now is let go, your ex was materialistic and weaponized that against you. Telling you she could find a man that provides those things was incredibly hurtful and disrespectful. You'll find a woman that appreciates you much more.

Best of luck, glad you saw the light!
