Codemaster,
Thanks, actually the idea of no going out with him alone was one that I had come up with early on, seemed that would easily put me in dangerous territory. So it helps to hear someone else bring it up.
As for codependency, guess it's something I need to think about. I am usually the overly independant one in relationships, but I can see that I have already invested more energy and time into this than seems reasonable. So I'll do my research. Thanks
