The question of whether a Pisces man will come back after no contact can vary widely depending on the individual's personality, personality traits, and the dynamics of their relationship. Generally speaking, Pisces men are known for their deep emotional connections and idealistic view of relationships, which may make them more amenable to giving the no contact rule a chance to work.
One important thing to consider is the Pisces man's avoidant attachment style. Since they can be elusive and dismissive, a no contact rule with a Pisces man might need to be implemented carefully to avoid causing unnecessary pain or frustration. It's important to be understanding and supportive of their need for space, while also making sure that you are not avoiding them unnecessarily.
Additionally, a full year without communication may not be necessary for a Pisces man to move on, as they can be pretty forgiving and understanding. It's more about how you communicate and interact with them during the time you are in contact., a Pisces man may come back after no contact, especially if you respect their requests for space and time, and communicate in a positive and supportive manner. However, it's also important to remember that relationships are complex and it's possible that they may not work out after a no contact period, regardless of the outcome.
