I'm going to tell my wife that I love my family more than my in laws and that my family probably doesn't care about her like they care about me
What in the world would drive you to tell your wife this?
She needs to hear it. I'm surprised they don't care about her. I mean they never got to even know her, they were always so busy with me.
You shouldn't tell your spouse that your family doesn't care for her. You're just going to upset her and create issues with her and your family. It's better just to keep that stuff to yourself to avoid creating unnecessary drama.
She needs to face the reality that I'm more worthy.
I don't see what good telling her how your family feels about her -- if it's even true. You sound like you have some repressed anger and jealousy that would be best explored in therapy.
