My soon to be ex wife and mother of my child has pretended since August that she doesn't have a cellphone. When it comes to our son, she calls from random numbers or her mom's number. It's frustrating because I don't see the point. She has my number. It's not like we talk. It's just for our son. What's the point of hiding her phone and her number? It's really immature to me.

tl;dr: I don't see the point of my stbxw pretending she doesn't have a phone. This is making coordinating for our son stressful. Does she actually think her phone is a big deal? It's just annoying to constantly guess who is contacting me. Plus I had her mother's phone number previously blocked because she was abusive towards me. Now she wants me to unblock it.
