So you hoped you were going to have a wonderful relationship with your beloved but it ended because you couldn't see eye to eye or for whatever reason. When one party wants to end it, don't argue, just accept the moment as it is now. What is good for one is always good for another.
When you continue to argue over who's right or wrong and try to persuade someone to your point of view, you're in bondage.
The end of a relationship releases both parties to their good so they can be the Love that they are. If your friend's good involves you then you will be reunited. If not, then you're both free to attract what is for your highest good.
In truth, nothing ever ends. Even if that someone is no longer part of your life, humanly speaking, you never stop loving him because loving is your nature.
