Bad. Bad. The bad thing about keeping up with ex-HD is that it keeps you from fully investing in your current R. I know because I had BIG problems with ex-H and kept up an occasional convo with a ex-bf and I only realized that he was my "back up" plan when he died in 9/11. When that happened my ex-H and I were divorced and I realized that I had kinda kept the ex-bf in my "back pocket" all of those years (even though he was happily married by that point).
Sorry for the hijack HP. I think that we all have our little escape routes and I didn't want to let this one go. I try to catch myself on mine too.
