I definitely get this. I’m 41 and was always considered the guy from my large group that everyone thought would stay unmarried without kids his entire life, as I’m a wild, traveling man that has dated a ton.
I myself was unsure of what I wanted, but eventually found a great gal and got married a couple weeks before I turned 40 and we just had our first kid 7 weeks ago. It is so different, and difficult at times but so worth it for me. It’s tough cutting back on some of the things that I love to do, but I’m starting to find a nice balance where I don’t feel like I’m lacking those things, but I’m still present enough for my family. I definitely felt people trying to pressure me about the “ideal” life of a wife and a kids while I was running around, but in general I don’t give a crap about societal norms or what people think about my choices.
