How to move on with the pain easily?

I am not certain as to how to continue living while my wife is cheating on me with another man. We don't have kids because I am not able to produce one. Due to that reason, my wife left me and went away with some other man. How can I stop myself from feeling blue? My friends suggested I should enjoy life by attending a foreign social events and date different women. However, I don't have the slightest idea on what they do. Does that even ease the pain I'm feeling? Help, I need the fastest process to get this over with.
