DO NOT, under any circumstances, buy or rent a place in a different country without fully understanding the legal implications. Talk to a L. With two kids and living in a country neither of you are citizens of, I imagine the laws are complicated. Don't allow her to take the kids back to Russia or wherever and put you in a bind. Make sure you know the law and fully understand the potential consequences before you make any living accommodation moves.
I agree.
Your job right now is to put boundaries around you and your relationship with your children.
