1. Be interesting - that means developing skills and hobbies other than vidya and 4chan.
2. Go to a traditional church. That's literally it.

I've been at my church for 15+ years and have watched nearly all the young people mingle, date, and get married.

Even and I daresay ESPECIALLY the ugly dudes who make even the merest effort can make it.

Just find a church that fits your beliefs. Worst case scenario you have to do Unitarian which is literally moral relativism with a Christian whitewash, but it's still better than jews, mudslimes, and pagan whores.
