i agree in terms of the house, you said this one is family land in your name only...so he moves out...
or he can buy it from you for full market value...rent it, sell it whatever you obviously dont want it anyway and now its filled with bad memories...
but do NOT just let him live there scott free/have it...and force you onto the other property (no matter how much youd prefer to be there)...
he has no rights to that proptery...
if you want the other property im sur eyour laywer could easily fight for that to ebcome your new home and you could either rent the family owned property or sell it...
and you want support not only for you while you get yourself sorted but for the lifetime of the children you have together.
dont give him anything
take anything thats yours and put it safe, he can have anythig thats specifically his, too, but anyhting of joint ownership of value (monetary or emotional) dont just let it slide.
it sounds like hes in the mids of a money induced midlife crisis and while im not a spitefull person, it needs to be made very clear to this man that its not that easy to toss away your responsibilities.
YOU and your kids are stronger than you will ever know, you WILL get through this together...
tell your kids you need them to simply love you right now, support them and theyll support you!
but you can and will stya strong, youll get through this youll survive and youll be even stronger in the future for it!
show that little girl of yours what REAL women are made of!
you WILL be ok!
