But your mother made ten tables, and all the sugar, tobacco and alcohol were given by the man, which was a bit excessive. How many guests budget in advance? What a waste. Besides, engagement is a matter for two families, and you can't give all the pressure to one family, don't you think? Of course, it's okay for men to spend more, but it also depends on the situation, such as the financial situation of your boyfriend's family. Well, you'll be at ease. If it is tight, I think you can still save it. After all, you have to live under your mother-in-law's nose for decades, and you can't freeze the relationship between mother-in-law and daughter-in-law for this matter, can you?
I suggest you two sit down and talk it over. Everything can be solved.
