Terrible
This is probably one of the worst stories we have heard so far on this list. When has anyone ever told you something even remotely terrible as this happening to a young couple? Your best friend enters the scene, steals your girl, and then marries her using the same ring you proposed earlier.
Now that has got to hurt, we are sure it would take someone years to get over the stress and trauma from something like that. Imagine the trust issues this poor man has now after going through all of that. We hope he finds the love of his life as soon as possible.
