Oh, dear. I'm not sure I like that. C-NESSUS on your MOON indicates your emotions could take a serious beating with this fellow if he's unevolved; the core of the pairing - the so-called 'identity' of it - brings out your most innate sense of victimhood: DEJANIRA.
I'd say to tread carefully, unless you KNOW you're together for the purpose of deep, healing work. Psychotherapy, for example. That SATURN-KARMA connexion points to how you're clearing karmic baggage; so I get the 'need' for you to 'be smitten' to undergo it all. Just be very mindful.
Are OPHELIA or PHILOMELA involved?
And how are his natal NESSUS and DEJANIRA? Does the composite 'hit' him, too? In other words, are sensitive points being activated by the composite? The more mutuality, the better.
