Doesn’t matter if you’re married or single, they’re all the same. A woman’s loyalty is with her feelings and emotions, not with you or the sacrifices you make for her.
Even if you’re the guy who sacrificed and donated a kidney for her, or gave your lungs to her to breathe better, there’s a high chance that she’ll still abandon you for a man she feels is better than you. Hypergamy is real, keep this in mind:
When a woman has feelings for another man, what you have done for her means little or nothing. That’s why I always warn men not to put too much effort in a relationship just to impress and keep a woman.
Elon Musk couldn’t stop his wife from leaving him. Jeff Bezos couldn’t stop his wife from leaving him. Bill Gates couldn’t stop his wife from leaving him. Who are you to think you can keep a woman who wants to leave?. What resources do you think you have to buy a woman’s loyalty forever?.
Even God Himself created a garden and gave the women everything, and the only thing He asked them not to eat, they ended up eating it. You cannot satisfy them, nor can they satisfy themselves.
When dealing with women, you have to take care of yourself first before you do anything for her.
