My ex is using a form of parental alienation on our daughter. My daughter and mom refuse to pick up their phones to communicate with me. I text, email, and call to no avail. It has been almost six weeks since I have spoken to, or seen, my daughter. I have joint custody and a visitation schedule of a couple days a week. My daughter is almost 16. What is the best way to handle this? My goal is to preserve my connection to my daughter.
