Ladies, I need some help! Someone talk some sense into me.

Here is the timeline:

I was with my ex for 12 years he is 6 years older than me and had been previously incarcerated prior to me meeting him. We had our son 2-3 years after we were together. When our son was 11 months old he got incarcerated and has been since. He was given a 13 year sentence. I stayed in our relationship until a few years ago. I couldn’t continue to put my son and myself life on hold for him AND I couldn’t get over all the cheating that he did when he was a free man. I’ve always felt that he can only be loyal behind bars but didn’t want to recognize the intuition so much so in denial and being naive. I was young and first boyfriend. Well I met my husband 4 years ago. Old childhood friend that has always had a crush on me. He’s amazing with my son his nonbiological son. My Sons admires him a lot. They are really close and he tells everyone that is his son. My husband and I have a 1 year together and my son tells people that is his youngest son. He has never told people that my son is not his. My purpose of this post is that sometimes I feel like I miss the street bad boy and someone that taught me a lot like my ex. Like I felt safe in some way. With my husband he’s never had an altercation in his life. I’m NOT thinking of going back to my ex. I don’t know how I can shake this thought. I’ve always dated older and mature men and my husband is nothing like it. Someone that was round about. My husband is very green. Any advice?
