A little annoyed

my Fiancé wants to use a wedding gift we just recieved off $250 to buy himself coils for his vape and things for his military uniform. It's suppose to be OUR money and to toward things for OUR WEDDING. Which is in 16 days. We could use the money for I dont know, tipping our cake baker or funding things for the honeymoon or something that pertains to the actual wedding.😒😖😩
