When a person purposely deceives or goes out of there way to hurt you.

When it meant nothing to the other person.

When then don't even value a friendship with you.

Im sorry someone has hurt you.

Do you have a question?

Time to let go of this-I assume it's about your exes-they're in the past and you should concentrate on building a happy new life for yourself now.
Only you can do that.

Make up your mind to truly move on.
