Yes, I agree with the previous post. In the US, even if the wife is stay
home house wife, when file divorce, she gets half of everything, including
house, car, asset.
In your case, you paid for full payment of the car and house purchased by
both families, you will get half of total asset. I think your husband only
said that because he does not really want to divorce you.
But I want to remind you, all marriages beginning with exciting/love, end
with dull life. If you divorce and find another man, fell in love/get
remarried, and have kids, 5 yrs later, the life will be dull again.
Pls think again about divorce since you have responsibilities for your son.
