Nothing is more important to a Pisces man than his relationship. He makes sure that he only has eyes for the girl of his dreams. Although he may find other girls attractive, it’s a natural instinct for him that he’s aware that he’s committed. It will hurt his pride if he does anything to hurt you. Loyalty means that even if you’re away from each other, you can still trust a Pisces man to behave and only have his eyes for you. It’s very rare that he will cheat on his girlfriend. His boyfriend duties matter. When you’re dating a Pisces man, you can be rest assured that he is only yours and you’re only his.
