There is something about the Pisces woman that likes submitting to her man, but she needs to make sure she doesn't lose herself in the process. He will be so romantic to her, and in return she will maker him purr. However, just remember this man likes sitting on the throne at all times.
He is Fire and she is Water, when you mix these elements, and one doesn't overpower the other, you get steam. However, if one is stronger than the other it will take the other element out. These two will constantly be having to find balance within their relationship to make it work. She would be a smart woman to run things from behind the scenes, which she will be able to do with her feminine charm. She may find it exhausting keeping up with how he expects her to be, but his adoration of her will keep her going. If they do get into an altercation she will just passively disappear, leaving him to roar by himself. If he hurts her too bad, she will swim far away leaving him alone and confused.
