I have a very good friend I’ve known since we were in grade school together who never had a partner the entire time we hung out regularly. He was just always a bit shy and awkward around women. I moved away from the city we both lived in when I was 27 and then about five years later he suddenly started dating a woman who had a son from a previous marriage. They’ve been together about maybe five years now and married for at least two. He’s become even more of a leftist since the start of COVID (he used to be just a generally left-leaning lib type and now is a declared socialist) and he went vegan, which blew my mind because he used to always just eat fast food when I knew him. So yes, you can find love and develop a whole lot more after 30.
