How to tell if your Pisces partner has a lover?

Decidedly promiscuous

Although they seem innocent and reliable, Pisces may surprise more than any other sign.
As they are hopeless romantics, often they confuse a passing illusion with the deepest love.
Worst of all is that they cannot say no in time; especially the females cannot resist the call for help of men who seem in need of affection and more than one takes advantage of this.
Anyway, discover a Pisces’ affaire is often simple: the languid glances and constant sighs betray the ladies; men, meanwhile, will walk more self-absorbed than usual or prolong their absence making up the silliest excuses.
