My children's mother let her new husband adopt my children without my consent
I have not seen my children for almost 4 years. My ex girlfriend and I had 2 kids together and things didn't work out. We decided to go our separate ways and that it was best for the children but promised I would still see them. She allowed me to see them every now until one day she told me she was leaving and wasn't going to tell me where she was moving with her new husband. Ever since then I have been trying to track her down, I now know she is in Washington and she has stated that her new husband adopted my children without me signing any type of paperwork. So basically my kids were taking right from under me and she will not accept the gifts I get for them or even a call over the phone. Please help
