I feel so misunderstood...

Prior to my marriage I had horrible experiences in dating and a couple of toxic relationships. I had alot of poor examples coming up so it took some time for me to learn. I married a good guy our divorce came about because after some time there was no more compromise. We had so many debates and arguments it just built up over the 7 years of our marriage my needs weren't being met so I wanted out

It was a smooth divorce we have joint custody, we co parent well and have sex on occasion. I enjoy being single I'm over relationships that is completely out of my mind. I just work, enjoy my kids and solitude. I am human and have urges so instead of getting a new body I go back to my ex, someone familiar and I know is clean yet I'm being demonized for it from my SUPER religious family... 😒

I could bitch and moan about how they are the whole reason I learned alot of things late in life, I'm always still in the process of unlearning every negative thing they taught me but I'm really getting into being selfish about how I life my life. I just want an outsider looking in perspective. Is having sex with my ex on occasion toxic? We get along so well he is my best friend but our love stopped growing somehow why is that so bad? We prepared our kids for the end of our marriage, put them in therapy they are managing well. It's been a year and half still drama free but how is having sex with him such a big problem?

PSA my tubes are tied and burnt I have no worries about getting pregnant

I also forgot to mention our kids are school aged so we only hookup when they're in school. Before we even started that was a concern and it is completely platonic, we just have sex basically fucking. No making love, intimacy, etc.
