Each of us (chooses) our own friends, lovers, and spouse.
You need to examine your mate selection criteria list! Why did (you) choose her to be your lady? Why do you want to be with someone who can't be pleased or happy?
There are over 7 Billion people on the planet! You have options!
The world may not owe you anything but you owe yourself the world!
"Never love anyone who treats you like you're ordinary."
- Oscar Wilde
Clearly if someone doesn't think what you have to offer them is "enough" then they don't think you're all that "special".
