What a coincidence — I proposed to my fiancee on Christmas 2017 as well :-) But you’re right about the wedding costs, they are astronomical! I think you’re making the right move by not powering down... steem is only a fraction of its 2017 peak. If you can find a way to barter to help pay for some of he wedding expenses that can help. For example, if you have translation, writing, web design or art skills you can barter for someone to do the photography, flowers, catering or music for your wedding. Good luck!
