What are they aspecting? Are they retrograde? Do you have a Libra or Scorpio as your ASC?
The 12th does represent things that are hidden or institutions (i.e. prisons, hospitals, etc...) also, hidden enemies, solitude, and the unconscious.
I am not seeing your chart, but from the very little information you have provided it seems that your love life is somewhat hidden or very private. You most likely idealize love and have an almost idealized image of what you would like your mate to be. If you are a guy you probably would like a woman who is very feminine and reserved. You are probably shy also, unless something else in the chart states otherwise.
With having your Jupiter in Libra in the 12th you could possibly make money doing some sort mediation possibly in the prison system, or dealing with juvenile delinquents. Maybe being a beautician in a convent.
LOL You see where I'm going with this. I am giving you a very general brief description of how it could express itself because I don't have any other information to go off of.
