Your two moon signs are 135 degrees apart in a Quincunx angle.
One of you may feel like you are constantly working to please the other, this may be the sign of a relationship that is out of balance so take extra care to watch out for this.
An imbalance could be created, however if you overcome this there is some compatibility between these two Moon signs. You share only a little bit from a feeling aspect. Your Moon signs indicate that you have conflicting desires however there is still a great deal of romance and desire between you.
Libra is typically a Moon sign of charm, tact, and elegance. Pisces is a Moon sign of sensitivity, gentle sympathy and respect. Each of you may find that you have just enough of the stuff that the other needs to make you feel complete, though the Libra Moon may have to learn to be careful with the sensitivity of the Pisces Moon. In the end however, it may be difficult for both of you to maintain your sweet loving nature for each other; you may end up finding fault with each other's own sweet ways.
