Thank you everyone, all I want is just a few others thoughts.

Him and I have been together for a while and I couldn't just break it off over thoughts. He's been my rock through some very traumatic events, but believe me when I say I'm extremely cautious. I still limit his alone time (with some subtle but believable excuses) I just hope I can find out one way or the other before this relationship goes any further. I would love for input from anyone in a similar situation. I know its a tough subject... I just don't have a lot f people to turn to for advice on this.
