Never Date a Scorpio 
Jealous, paranoid, and possessive - deep down, your Scorpio will never trust you.
And even if you are very trust worthy person, Scorpio's paranoia may drive you to act out.
Instead try dating: Aries, Gemini, Libra, or Sagittarius

I know. Mental cases
(ps: Aries are too arrogant. Libra's are too twisted and tends be jealous too. Saggis tend to be players and say the worst possible things at the worst possible moments. Male Geminis are psuedo intellectuals and commitment phobics. What a bummer
