Maybe not. I am not even really sure what that means. If it looks something like following a wife or girlfriend around with a grocery cart while babbling inane nonsense like I see so often, count me out. I already have plenty of different types of relationships. The only one that I am missing is the lover that doesn’t nag and isn’t a net drain but I can get those on demand right now.
I know it sounds very capitalistic and transactional but I truly don’t see the point otherwise. I already have kids, I am not going to support someone else’s and I know there is a greater than even chance that we will get divorced even if we did get married.
What is the benefit to having a “mature relationship”? Almost everyone I know that has one isn’t happy with it. I am admittingly self-serving and not in the business of making myself unhappy just to conform to other people’s expectations. If you want to pick someone up at an airport or hotel bar, just look for a wedding ring. Your chances are better if they have one.
