Can you be happy single?

Hi so I'm 23 and going through a crisis. I've achieved everything in life that I wanted and I had an impact on. I went to my dream uni to study CS, have been working as a Software Engineer already from the second year etc. but I've never had a girlfriend and was also the guy that girls would not really crush on despite being tall and not that ugly. So lately I wanted to find one but it is very tough, I've downloaded these dating apps but the girls there have so much attention from men that they don't even bother to go on a date and are very flaky in this matter. Maybe I should try talking to women IRL or just accept the fact that I'm a man that women just don't want to be with and try living a happy life alone?
