Sorry to say but this sounds very ridiculous, it clearly shows you are not yet ready to marry. Perhaps this should be a wakeup call for your would-be bride to make better decision 
You should already know btc price will start to rise rapidly at some point and should not be enough reason to halt any real life event for.
I hope you can take advantage of the upcoming bull market because some people can get carried away during this period and ended up not doing as they intended.
