planetary positions and soul mates

So i was told once that an ex-boyfriend of mine and i had a "soul mate connection" due to certain planetary positions in our charts. I would say that this statement was in a way very correct since he was someone i considered my best friend, and we understood each other very well. but in many ways i didn't think of him as my soulmate. i think some planets were off according to that.
anyway, my question is, what sort of planetary positions provide the best outcome in a match? and does reality confirm this? anyone have personal experiences to attest to this?
for example, is the best match if your sun is their moon sign and vice versa? should your venus signs be in the same element?
for my sort-of "soul mate connection" we both had earth sign moons (not the same ones), different sun signs, my rising sign was his sun sign, and we both had earth venus signs (his venus sign also being my moon sign and me venus sign being his moon sign).
do you think these formulas are consistent? any real "success" stories of connections so deep that actually were consistent with all of the different planetary positions?

oops posted twice

i see. is there a website you'd reccommend about this?

Venus conjunct pluto.

i would really like to get an analysis too shaks, if you wouldn't mind. i'd really appreciate it.
