This thread hits so close to home. I fully understand the pull towards these relationships despite the awareness that they will likely bring more pain. I also understand the struggle of wanting to get back into them and the knowing that you shouldn't. I am not sure there is really an easy way to stay out of them. The only way I have managed to do that is by reminding myself of all the past pain and keeping the fear of that pain alive but I don't think that is a healthy way to do that. I really feel for you at this moment. Stay strong!
