Frankly speaking I always found unwise disclosure natal charts in the open. A soul's map is indeed the paint of one's true nature, but they are not the sole outcome. Mother Lilith once said: "Nothing is written on the stone." meaing that you actions, both material and spiritual count a lot.
Let's imagine one finds out the marriage would be impossible, he/she will doubt maybe leading to break up. Or if he/she finds out the marriage will be great they will stand still, cause they feel no work is needed, and this will probably also need in an emotionless relationship, possibly leading anyway to a break up.
What I'm saying is that one has to work regardless of the outcome, energies and planets are costantly moving and so should the individual. "Happiness" and "Love" is not a passive winds, it needs an engine.
Altough there could be strong minds, thoughts can hunt you before the sleep regarding an open statement about the charts. Especially cause you need the whole picture not just a couple of aspects. Other planets, houses and aspects count too.
