WAW moved out, spewing anger, trying to detach

[Ralph88]

Document every time she doesn't answer and your intent was to speak to child. Text her before and notify you are calling to talk to the child. Take screen shots of phone. Email her and tell her you tried reaching child on x days at x time. Attempt to solidify a specific time to call in the email and continue calling. It will force her hand and give you proof of her keeping the child from you. On your side though, when you do call to speak to child, do not talk about anything else with W.
