What is a different perspective for not having a partner?

I currently don't have a partner and haven't for a while. All of my friends are currently dating and seeing people, and they act like it's the best thing that's ever happened to them. They're suddenly so much happier and fulfilled now that they're seeing someone.

I've tried dating and I realized, I just don't have time or motivation for seeing anyone. I have no personal desire to have a partner, but being around all my friends and hearing them constantly talk about how wonderful their bfs/gfs are has made me feel left out. People also question why I'm not seeing anyone.

I need a new perspective to stop making me feel bad for not seeing anyone. Like "without a partner, you have more time for yourself," stuff like that. I just need to get out of this rut of feeling bad about something that I don't even want lol
