My ex-husband was abusive, including threats against our son, and I moved out of state. He ran me out of money so I was unrepresented at trial and he was given unsupervised visits in Spokane. We are now one month past that ruling and he had his first visit. He refused to tell me where he lives, but I know he is not at the address he has on file with the courts. He also refuses to tell me who he is living with or introduce me to her (his new girlfriend). Our son is two and cannot tell me what happens when he is there. My ex is also not responding when I ask questions about how he is doing, etc. None of this is specifically required in our parenting plan - do I have grounds to modify?
