> I let my social life dwindle and I don't know fucking anyone anymore

I suppose this is proof that us guys are dumb as bricks compared to women. This is a typical story. In fact, it's the norm.

By comparison, most women don't let their social web wither once they have someone else.

Also, I agree with >>3. Also try sport clubs. Or Toastmaster. Or dance school. Or...

There's plenty excuses for "networking" disguised as something else. If you want to meet people, you actively have to pursue it.
