What are your thoughts on being single at 30+ while your friends have kids and families?

Most of my friends and relatives are married with kids, settled into family life, while I’m still single. I don’t hate being single, but my past relationships didn’t work out due to cheating, heartbreak, and other toxic issues—guess I’m just unlucky in this area. Sometimes, seeing others with families does bother me, even though my family doesn’t pressure me about it. These feelings come and go, and I try not to overthink them.

For men 30+ and single, how do you handle these feelings?
