I'm asking since I've been reading a lot of advice here to people in my same situation, but did anyone actually ever solved this problem? In this case, any specific advice?

I really cannot manage to find a girlfriend, or even a girl to date: in the past I've met interesting girls, but every time they were engaged or not interested, or both. Now that I'm over 30, it's obviously getting more and more difficult, since every interesting girl over 25 is engaged, and every girl under 25 is a bit outside of my social circles and environment.

Thanks to anyone who will help!
