Greetings, Brother / Sister!
Romantic relationship and else is your choice and depends upon how you deal with your energies not merely on natal chart. In natal chart we can have many beautiful signs yet realize none of them or use only evil side of them, if we lack ethic and nobility. I saw a chart full of extreme genius signs (including Pluto in 12th as well) Mozart's type stelliums etc. Chart belonged to a pinko fag who realized in nothing but prostitution & cuckoldry.
Pluto in any water sign is very powerful spirituality sign if much hard work applied, might be black hypnotic, professional manipulator or abuse victim/perpetrator in lower octaves, and powerful magician or psychic - in high octaves. 12th is of hidden enemies, so to have Mars, Saturn and Pluto there might be dangerous and needs sublimation, mostly into any and all kinds of spirituality & secret work / societies.
