Some of us have had unhappy marriages which might have been avoided if we'd paid attention to the red flags or had MN to show us what was wrong in our relationships before we sealed the deal and had divorce to get through which is a hell of a lot harder and more complicated than leaving before the wedding.
No one wants you to be unhappy. No one wants you to end your relationship. No one wants you to spend your life with a man who either has good intentions but no backbone, or one who cares more what people think of him than his wife or his and his wife's financial security.
Do nothing, let him waste a load of money you don't have on a boys jolly he won't enjoy, let some flash pretentious dick head ride roughshod over your wedding plans so you can't afford a honeymoon. Go into your marriage not knowing how to communicate effectively through conflicts.
But you know you asked for advice for a reason because you're not happy with the status quo.
I'm now very happily married to a man who puts me, us, our life above everything else. I know what a difference it makes being with someone kind, mature, considerate and with the strength of his convictions. The idea of going on a holiday you can't afford doing something you won't enjoy to impress someone you don't really like is madness.
This is your opportunity to work things through together and come out stronger and with faith in the future you'll have ahead of you.
