You need to go for counselling, you are not managing your family properly, your wife is suicidal because of the way you treat her

Hmmmm....

A wife who spends rent money without an ironclad reason (like the child is dying) and husband's consent im this economy is extremely wicked.

OP should report her to her family and drop her there for Christmas till she is ready to disclose what's chasing her (if any because it could be a stunt to garner pity) and what she spent the money on.
