Oooh this a deep connection for sure.

Well you got your moon in Scorpio and we all know Scorpios and Cancers are the sweetest thing. So you're lucky there. Only problems with these two is running and hiding in their shells when they're hurt which happens quite often when there's no understanding between the two. Try not to do that. You're gonna have to communicate through problems, seriously. Subconciously, Scorpio and Cancer know each other well and have a telepathic understanding of one another, which is priceless.

As far as Leo is concerned, watch out that you don't get too self-absorbed because Cancers needs just as much love as Leo does to thrive. Your Cancer should have no problem worshipping you, his heart is as big as yours, but you'll have to reciprocate that or you're gonna have a crabby, snappy Cancer on your hands.

As far as learning and growth, you both can learn a lot from each other, Leo teaches Cancer self-assurance, Cancer teaches Leo humility, Cancer teaches Scorpio how to trust, Scorpio is Cancer's rock, so this is a good one to me.

i've heard aries and libras are big cheaters.... don't know if that's true, but maybe that's one of the contributing factors to his infidelity?
