Ok let’s talk budget!

So obviously the first (awkward) convo I HAD to talk with my parents about the wedding was BUDGET! My parents are both retired, and don’t “necessarily” have the funds for a full on wedding. (Keep in mind we are pulling this off at around a 12k wedding- which is pretty much a decently “budget wedding” in Connecticut.) I asked my fiancé to talk to his divorced parents about contributing. His mom offered to pay for a dj. Great! She works two part time jobs, and I was thankful for any contribution she made. He asked his dad if he would help (pretty well off) and his dad asked for the budget. I emailed the VERY detailed budget.A month after sending, my fiancé awkwardly asked- soon can you contribute at all.. and his dads response was, well if you don’t know the number of guests on the grooms side, how would I know how much to give? Basically saying we would find out his contributions about 3-4 months before the wedding when we recieved RSVPs.

SOOOOO my question is, how did everyone else handle groom contributions? Was there any conflict due to old school traditions? How did you resolve any issues?

thanks in advance! Xx
