Just another thought- I'm my husbands 'new' wife. We will leave everything to each other in our will because all we really have is a house. Everything of ours is joint. If we were to leave it to my husband's children I'd become homeless. When the second one of us dies it goes half to his children and half to my family. So they will get something eventually. Also, I put the equity from my own house into our joint house, as did my husband. So the house we own is equally ours. That's why it will go half to my family and half to his.
Sorry that you're having a hard time with this. I hope things will improve for you all. Best wishes.
