I agree with Sandi2: I think you're fooling yourself on the innocence of this re-connection. You're entering a very slippery slope. Sharing our concerns is a fast track to emotional attachment. Believe me, as a student of seduction and attraction!
Be very careful to be honest with your actions and intentions. We've had other people here trying to cover their actions with words: "I'm not trying to badmouth her, but she's an awful person." See the attempt? It's very important that you be honest with yourself in general. People will quickly see what kind of person you are if you sometimes say one thing and do the opposite. Part of this process might happen in your subconscious, so dig deep. We do it because we're afraid of facing the consequences of our actions, for instance. Here, admitting that it's a risky relationship might mean cutting it off at a moment where you feel you need the support. But realize that in the long run, being honest with yourself (and others) is what will pay off the most.
