Well, it is much easier to refuse than to change my mind because of the power struggles in our M. He can't MAKE me pay the extra bills and more than I can MAKE him pay his share. So, if I refuse to take on the additional expenses, it is much easier than trying to get him to understand that I've changed my mind and therefore he must take the bills back. Wouldn't work I 100% guarantee it.
