If you leave him desperate to have a corner in his heart but his feelings will smoke and burst into fire burning in his chest don’t call it love. It is a type of vendetta, the desire to take revenge for the revenge. Perhaps with all the consequences that come with it.
If a partner leaves it is better to make him/her right. It will be as if you lift him/her up a hill which (s)he will be easy to roll down from back to you. If you make him/her guilty you will find yourself up the hill, and when (s)he wants to come back to you (s)he will be faced with the choice whether to climb up the hill to you breaking his/her nails or settle down there in the valley.
Relationships end not because one gave up, but because (s)he had nothing except for this struggle and surrender, (s)he had nothing interesting in stock.
