When my fiancé and I got engaged, my future mother-in-law told us she would cover all costs associated with the rehearsal dinner so we did not include the cost in the budget we created. Now she just told us that she's spent a ton of money on things for his sister's newborn so she isn't sure she will have the money to put towards the rehearsal. My fiancé and I did a ton of research before this to try a find a place within the budget she told us she wanted to spend, but now even that seems out of the question. In order to book the place we were thinking, we would have to pay half up front which is $500. I am currently looking for a new job thanks to Covid so we don't really have the money unless we were to put it on a credit card. Having the dinner back at someone's house isn't an option because everyone lives at least 1.5 hours from our venue. What should we do? As a side note she hasn't really been effected by Covid because she collects a very nice pension (close to $4,000 a month) and she just started collecting social security that she wasn't receiving before so her financial situation has actually improved unlike us.
