My husband is in Iraq and has given me full power of attorney and said he is giving me his rights for our summer visit. The EX does not like this idea and now will not allow me to speak ot the children. I have had a relationship with these children for 3 years and while he is in states everything is fine but now he has left me in charge of paying for childsupport and all medical copays, she will not answer my phones calls or letters to the children. WHat can I do?
