I've been divorced seven years joint custody of my son the whole time. My ex constantly tries to get back together. I have consistently said no. Clearly he has no legit concerns about my parenting or he would not want to be back together. He is now filing for sole custody and when i texted him to find out how we could avoid this, he sent a message saying he has given me numerous chances to "not let it come to this" by raising our son together and "seems now it's hard for you to help yourself" I'm not sure if I would "win" a custody battle but can i show the messages to the judge? It kind of seems like a bribe to me.
