Falcon, I probably should reply on your thread, but if Tman doesn't mind I'd like to address what you wrote here.
I'm going to give you my honest opinion. It's that should you get back together with her I think it will be too soon. My sense from what you said is that she hasn't grown...in fact she's more irresponsible. Is that incorrect? I just have this sense that you are a convenience for her, but she'd still see herself as divorced and would cheat on you. I hope I'm wrong. You have an opportunity here to look at what's best for you as well. If she is only interested in a roommate I'd tell her no. If she wants to try again with you I think she needs help with her problems or history will repeat itself. Just my opinion obviously.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
