Relationship Problem

A pain that will never go away...

How long does it take to heal?

You're not seriously looking for an exact time, are you?

That depends on how deep the love was, on how deep your understanding of life is, how sensitive you are. No real answer.

I know what you're going through and a lot on this site do too.
Fake it until you make it. Live your life. Be happy on your own. That day where you will be happy will come... don't force anything...it'll happen.
