So me and my baby's father has been together for a rocky 3 years. We tried planning our lives together which consisted of me moving to Alabama with him and his family with our son to raise him together, however, it only lasted for 36 days because just last week i came back to Cleveland Ohio to stay with my family. During my time there, things started off perfect but then got extremely rocky. His attitude changed, he became extremely disrespectful, he started hanging out a lot and always left me home with the baby by myself. Most of his family was nice but then there were a couple that wasn't. After things went bad, I took my son and left. Shortly after getting back, despite how things ended we still kept communication for the sake of our son and agreed that we'd remain civil. One night I decided to call him and update him on our 9 month old who had just came down with a bad cold. He didn't answer my call but then called me back hours later when he was around his male cousins. For some reason, something told me to investigate. I still had access to his messenger from when we were together as a way to "prove" to me that I could trust him. When I signed in I so happened to find these messages between him and and his 17 year old cousin, the daughter of his father's brother. Mind you after doing the math, all this took place during the time I was trying to call him. I never in my life would have ever suspected any of this while down there. This girl watched and held my child. My child's father is 23. After approaching him about it I told him that I wanted to cut off all contact permanently and now he's threatening to fight me in court for joint custody. In Alabama, age of consent is ofc 18, so not only is it incest, but pedophilia. What should I do?
