Let them...

They want to break up with you, let them.

Don't beg them to stay, hold the door for them on their way out.

They stop talking to you, let them.

Don't ask them why, it's their choice just make more friends.

They pick someone else over you, let them.

Their rejection is not a representation of your worth just focus on you.

They said they don't love you, let them.

someone else will be crazy about you and as long as you love yourself that's all that matters.
