For magic, it does not matter how long ago the separation has been. It is unimportant for the effectiveness of a Return Lost Lover Spell, whether you have been separated for a week or 20+ years ago. Also it does not affect the outcome of magic. Just because you’ve been separated for a while does not mean that the magic takes longer to produce results.
When it comes to past relationships the old saying that, time heals all wounds, most often turns out to be true. But sometimes there is that one special lover whose memory sits deep in our heart and who never really fades from our mind.
Perhaps the breakup happened long ago or maybe it was a more recent separation, but there are many reasons we might feel that this one person is lost to us forever. Bad feeling underpins most breakups, misunderstandings can play a part too. Yet it is sometimes also the own pride that prevents someone from taking steps to fight for the broken relationship.
