I have a Scorpio stellium in the 6th, ruled by Libra:Sun
Moon (21 degrees Libra, semi sextile Sun)
Mercury (r)
Venus
Jupiter (0 degrees on the cusp)
Pluto
.. so my answer might be bias but I can chime in a bit.
My mars is in the 7th conjunct Pluto (Pluto rules my 7th) also sooo yeah..
not to mention Jupiter conjuncts the stellium!
But I take love very seriously and my main motivation is taking care of my partner and making sure they're happy. Since my moon is in Libra though, I think this shows my need for it to be reciprocated for that balance to satisfy my emotional needs.
But caregiver? Definitely. The 6th house is the house of Service after all. I want to assist my partner in every way possible. I want to know I'm making their every day grind easier just by helping out in any and every way I can. It really makes me happy knowing I'm useful to the people I care for... but that Libra influence forces me to examine both sides.. so although it is unconditional, I recognize self love and I deserve care too.
6 is even said to be a perfect number because when adding all of its factors, you get the same number you started with. (1+2+3). The number 6 represents balance.
