When do you never go back?

So here lately I have been talking to my ex more and more and Im thinking soon we may have the what went wrong and should we try again talk. Then only thing is when do you never go back? Im going through that period when you think should I even allow that talk to happen. Or should I just say no now, I know when he broke up with me through an email then and there I said I was never going to go back. Now though going through our relationship I feel that sting of what if. What if I go back and things work out this time. What if they don’t what if he didn’t really work out his fear of commitment and he runs again. Do I really wanna go through the heartache all over again? Is he really worth the risk of pain. Then I think am I really so different from him. Am I the one who is running now? I guess no matter how many times I mull over the questions in my head I will never be fully satisfied. I will never really be not scared or even ready for the risk. But isn’t that what being in a relationship is risk and without the risk is it really even worth it. Someone told me once follow your heart but is that what any of us should really do. So many follow there heart and never get any were but on the 2:10 to hell( yes that was a play on the movie 2:10 to Yuma). I guess we all just have to do whatever we think is right and see what happens. After all if we never made mistakes we would never learn how to better ourselves. So I guess that’s what I will have to do. Just thought I write this on my blog for ya’all to read. Who knows maybe it will help someone else cause I can’t be the only one who over thinks everything!
