As a Non-English speaker, my advice is to try some language exchange services. There are a lot of girls out there in their early 20s who want to have a relationship with English speaker like you. Learn a new language and make new connections with new people. A good travel, or new business opportunities. Who knows the future? Being unmarried also means being free. Take advantage of the privileges you have.

Mixed bag. Meeting girls in another country is fun when you're traveling and you're 18. It can be depressing if they don't understand your culture and you don't communicate well. Sometimes I can't even understand girls from my own country anymore who are ten years younger than me.

Great advice, learning another language gets your brain going and into social situations. He sounds lonely.
