Hello everyone!

My brother is going on a 6 month deployment in a few months, and his wife is doing some things that raise alarm bells for myself and my parents.

As a short backstory, they've been married almost three years but only got hitched because she got knocked up after only dating casually a few months. She is very controlling and manipulative (i.e., she once threw her rings at him because he wanted to go have dinner with our dad).

So rather than stay in the brand new house he just bought for her and hold down the fort, while he's deployed she is going to pack up shop with their toddler and live with her mother for all six months of the deployment several states away. She recently got a new car, and borrowed the money from her mother for it, titled it in her mother's state (she's refused to change her residency to where they are stationed), and put it on her mother's insurance policy rather than the one my brother has even though he's paying for it. She has not worked their entire marriage but just got a job working remotely at her mom's company part time.

All of these things have happened/been decided in the last few weeks. One of them in isolation (except moving away IMO) wouldn't be cause for concern. But all combined it seems like she's positioning herself to file for divorce while he's away. Does this raise flags for anyone else? Is living elsewhere during deployment something other military wives do? Or is this out of the ordinary?

Thank you for reading and for any thoughts/advice you have.
