Heartbroken, huh?

The only thing that you can do to forget a person is just to ignore everything about them. Yeah. Of course you will somehow remember your moments, sweet moments with them but it will take only maybe a few days. Don't you ever regret met him/her because they made you happy, right? But sometimes only by hating that person can make you forget them so maybe you should if it's the only way. Just don't hate too much like you will kill them. Just hate the bad things they did to you.

Always smile, think positive and cherish every moment.
