Pisces does not like those moments when they know that something could end badly. Run away from situations that may end in conflict. So if he has to let you go, he will do so in a very respectful and intelligent way. If he no longer feels anything for himself or yours has no future, he is going to let you go without you noticing. It will do it in a quiet way. At the end of the day, there is nothing wrong, because that way you save yourself the explanations.
For Pisces it is very difficult to go through that bad drink in which they have to say goodbye and say goodbye to you. It is not because Pisces does not want to give you explanations, but because he prefers that the relationship does not end badly. He knows that this is not an easy time and that is why he decides to do it that way.
You may notice that one day Pisces stops talking to you or you feel that you no longer speak as much as before. That it is no longer the same as it was before and that the romance and passion is over.
This is not a sudden change that happens from one day to the next, but it will happen slowly. So slow that no one will realize what is happening. For Pisces it is much easier to do so, but if you need to explain them, Pisces will always accept them with respect. For Pisces, the world is a place where they come to enjoy and be happy, therefore, they save those moments when life is not like that. Pisces faces a new day and better than the previous one.
