Is AUTHOR wrong in the post ? POST : I can’t have kids.

I’d always looked forward to having kids of my own, and it devastated me to find out that I can’t. I honestly felt like the biggest failure in the world, and I felt awful because my wife also has always wanted kids. I’ve thrown up the idea of adopting, which she likes, but she also wants to experience pregnancy and childbirth. I personally am offput by the idea of a child developing inside my wife that isn’t mine. I don’t know why I’d have no problem adopting, but for some reason I don’t want my wife to be pregnant if it’s not my doing. I want her to be happy, but I’m not sure if I could go through this

Am I an asshole for thinking like this? This questions tears my mind.
