Hey Beautiful, I dont know if I am right or wrong, but I believe that we see them subconsciouslly as "Our failures", and if we give them one more chance, life will become all fairy tale and white picket fences. I would say RUN dont look back, now you are out of it, why go back, especially he was unfaithful. Thats the pits in my books. Focus on yourself, and find what makes YOU happy without him, you have come so far, and that first break is very hard to make. Go forwards, not backwards. of course, it is very easy for a stranger to give advice, but I have been in your shoes, maybe still am.
