I think the question “why are you single” is just a popular thing right now. You aren’t required to have an answer, but it is an interesting question to ponder on your own. I have several answers. Relationships require time and effort, and I haven’t found a woman who merits all that time and effort. I haven’t met a woman with whom I share a romantic interest. I’m just not as desperate for a relationship as I was when I was younger.
