What is the best treatment to handle a jerk?

A colleague of mine came to me today telling me a story...

She's met a guy recently, whom she thought she could start a proper relationship with. He was so nice to her and of course took really good care of her during this period of courtship. She kept telling us he is a good catch; although he doesn't have the looks and is much older than my colleague, he has got a stable career, is very capable & knowledgeable, has a good family background and etc. She was almost stepping into this relationship until somewhere last week, something happened to the two of them. He tried to proceed further, more than what normal friends should be behaving, and she rejected him. Ever since then, he stopped contacting her.

Now she came back telling us she felt like an idiot as she really thought they could be more than friends and just 1 night, he has simply changed. She thought of calling him to talk things out with him or even sms-ing him to scold him. She came asking us what should she do and what she should not be doing. We told her that he's obviously a f**king jerk... The best treatment to handle such f**ker is to simply IGNORE HIM!!! Why should she let such f**ker disrupt her life? She should resume her normal life as if this idiot has never appeared before.

Isn't that the case?....
Anyway, I hope all f**kers in this world will have their rightful retribution.
