I'm a Pennsylvania resident and have ended a 5 year relationship with my 4 yr old daughters father.There has never been a formal custody arrangement through the court system but my daughter does live with me. He has 3 other children 2 of which he has never seen and 1 that he sees on occasion. He takes his daughter at his convenience stating he has no time because of work. He now lives with his new girlfriend and they take her son every weekend. I've been given the oppertunity to move to Tx to better our lives and start over. There's no support order but he threatens me saying I will never take his daughter from him.Can he stop me from leaving the state? I'm desperate for advice.
