Its sounds like you are not even together.
The thing is when the baby is born and if he still is like this, theres going to be a point when you need him and it will be a lot because ive got 3 kids and its hard work, especially with a baby. Its going to be really hard and upsetting for you if his phone is off or he has done a dissapearing act, and continues to. Imagine if you want him there for the birth and his phone is off.
Plz dont think im being negative or trying to upset you or out. But with you being pregnant just be careful and think of yourself and the baby before anyone else.
