Hello gentlemen. I'm hoping to get some advise regarding my ex moving to her new bf's house with my 5 y.o son.

We started our separation process with a mediator a few months ago and later today we have a session to finalize our divorce. I'm at peace with the divorce itself but I'm worried for my son since the transition between us not living together, her getting a new bf and moving with him took less that 8 months. Not only that's a lot of changes in a short amount of time, her decision is nothing but irresponsible and selfish. She already signed the papers with the landlord saying that she won't be living there anymore, she told me that her decision to move was "too fast" and that she's been very "stressed", she's moving to a different city about 2 hours away, she has no job and her bf already has 3 kids (all minors).

Has anyone gone through something similar? What other concerns should I bring up to the mediator to ensure my child's well-being?

Thanks
