How come society automatically views you as a loser if you don’t have a girlfriend/wife?

No matter what you do, if you cannot attract any woman you are automatically placed at the bottom of society. I will have conversations with my friends and they’ll suddenly shift to what they did with their gfs then give me looks at pity for not being able to attract any girl. I have also had moments where I get to know other guys and they slowly figure out that I cannot attract women since I never bring girls around them/post them on social media and then they leave me bc they assume I am weird.

I have plenty of achievements in my career, I stay fit, I volunteer because I like to help others, and I play multiple sports competitively. All these things should be great achievements but because I can’t attract women I am a loser who they shouldn’t be friends with.
