Mine is Yours, Yours is mine?
Partners confident enough to deal in money as per their will are very few in number. Soon the "mine is yours, yours is mine" change into 'mine vs yours'. Women feel their guy will spend all the money on gadgets that will rarely be put into use. But imagine a husband getting a heart attack when his cell phone beeps with a text which shows thousands of money spends on just eating and shopping.
This will soon create differences, as neither of them will tolerate such gesture, as they earn individually.
