He is. The living expenses he is paying for are the roof over his head, not hers.
The law is what it is. I can't change it, but since it is not possible to pay for two sets of housing, all that is left is not to have children.
If you honestly think that the money he pays me each month covers the mortgage, the monthly bills, food, clothing, etc. etc. then you are sadly ill informed. I'm sorry d-lion but this is something that has really gotten under my skin. What would you suggest?
