Postponing?

Basically I would have enough money myself to pay for our wedding. My FH is concerned he cannot contribute much money since getting his surgery bill and needing a roof repair or replacement. I told him I’m fine paying for it all but he’s thinking of postponing the wedding until he can save money. My concern is I already have 3k in deposits and I don’t want to lose out on that. I’ve also told him I’d be willing to help with the roof costs. Any advice would be appreciated.
