I am a Libra and my boyfriend is a Pisces. We look up the constellations, our constellations are not harmonious, and he is religious. What should I do?

The constellation has nothing to do with religion.

A person's personality is composed of many factors, such as constellation, blood type, parental inheritance, living environment and so on. It is ignorant to say that two people are not suitable just because the constellations are not harmonious. If you believe that you love each other, then support each other and create the myth of love together. If you break up just because the constellations don't match, it only means that you don't have true love.
