I'm trying to think of a classy way to ask for money to fund our honeymoon instead of gifts?? should i include a card while sending out invitations?? or have something at the wedding? please help a sister out

Hi ! My fiancé I know very little is 10 years older and will probably work a lot. I'm younger - I'm 26 and I want to play, come to parties. But only with husband! I do not trust, "friends". How do you flatten my boyfriend that we are young to sit at home and work all the time? Is a boy of his age going to bars with his wife?
