Oh, there's a chart drawn up. OK, it's like natal, you read the houses and aspects.
Yes like the op said first look at ac, sun, rulers. Also Venus and mars.
You might want to add eros and psyche for this, and look how they relate (eria to psyche, psyche to Eros)
Other key areas: 5th house: kids, play, dating. 7th house: relationships. 8th house: other peoples money (if your thinking rest if your life guy). Is it compatible with the ac.
Do you want to see where you are both heading, is that compatible. Spirituality, is that compatible.
Will it last? Well no matter weather you are or are not compatible, you determine if it lasts ie not. The better question there us often should it last. Is it a good choice (for both people).
