I'm in my 20s. I have had several terrible experiences with men. Never been asked out. It seems every woman I see gets a boyfriend, and I get nothing. I heard most women get asked out. I hate seeing couples in public reminding me of what I don't have. My brothers get girlfriends left and right. What is wrong with me? I try to be nice and dress nicely, but nothing. Maybe I'm not attractive enough. I think I hate men.

Cheer up!! You’re still young and beautiful someone will find you sooner or later don’t give up

If you think something is wrong with yourself, reflect further. If you believe it's due solely to external factors such as your appearance, you would be mistaken, but your attitude towards romance will play a role. Don't rush too much, and if you find someone you like, don't always wait for them, they won't always take the hint, no matter how obvious it may seem to you. While men are considered the more likely one to ask others, they can also be notoriously dense much of the time, nobody wants to ask someone out if they don't think they have a chance. That's just setting themself up for failure.

TLDR: Patience is key, appear interested.
