I might've been with one for a long time. I say maybe because I never looked deeply at his chart. Just noticed planets in 12th house and moved on. I don't believe he kept a lot of secrets from me personally because as a Taurus, he really had nothing to hide. Yet there was this secretive nature about him. He kept an anonymous phone number (back in the day of land lines) and was fierce about his privacy. I always found that odd but respected his space. No, didn't turn out to be an axe murderer (otherwise my Scorp dominant chart would find out). A psychic told me however, that he was a hard person to read. I'm not one to tinker with him psychologically but we were broken up then and that was that. I sense it was more his emotions that he kept from the world anyway. Sorry, long story.
