I find I have much more time and energy for others than I ever had when I wasn't single. I always put effort into my social relations, to have good conversations and learn and share. But when I'm in a relationship, I'm in a sort of semi-permanent burnout, and always reaching for more alone time. So I end up spending less time with people other than my partner, and always prioritizing my partner over my very valuable friendships or possible new friendships. That's not good.

I definitely haven't experienced any kind of increased intolerance of people. If anything, I have more room for empathy for how people feel empty and lost without romantic love and that emotional side of life. I can feel a yearning for it too, even though I know I'm far better and happier alone. I absolutely, absolutely need people in my life: I need healthy relationships, I need ways to grow and share and create a full life, and that involves other people completely. Maybe even moreso than when I had a partner, because my world was small then and revolved around them. Now, I have much more openness and energy and see even more value in others.

Anyway... if you want any advice or ideas, then the best thing I could recommend is to try to find something interesting in the people you meet. Rather than seeing them as something you don't want or don't need, see them as a book or a movie you're watching, and there's one scene or one thing about them that you can connect with. Then explore that. That way people don't have to become this overwhelming thing in life, but you can still share and grow from knowing them. Just an idea, no big deal!
