You don’t want children. You just want to feel better about yourself, that’s all. Like “look, I’m not smart nor pretty (that’s what you wrote about yourself in a comment above) but I have children, my legacy!” I can explain you about why do people (truthfully) want kids. Because they want to be in their children’s life. Because they want to experience their kids first step, first laugh, first word. Because they want to teach them everything they know about this world, and the most important of all, they want to love their children with all their heart. And I would understand you and your feelings if you would list at lest something resembling of what I wrote above. But the only thing you do is to complain about how you want to feel good about yourself having kids and how life’s unfair that your wife can’t produce them. There’s not a single drop of love and understanding regarding your wife’s feelings. Not a single remorse about what you can actually give to your “future children “. Just “me, me, my beliefs”. So, OP, I would highly recommend you at least to stop lying. First of all, to yourself. You don’t want kids. You just want to feel a void inside of you that you created yourself.
