To love is to be able to wait. It is not waiting for something, getting worked up over it or trying to comfort yourself with the thought that in the end your closed one will come back and “explain everything”. It is not like this. To wait is to trust. To trust your closed one’s words, actions, behaviour. To wait is to believe in this person without keeping him in the shed of your fear.
If you are able to wait like this you will never be alone.
