My fiancee's sister and brother-in-law are struggling financially, and
they live on the other side of the country from where our wedding will
be. We know it will be a major strain for them to afford airfare for
themselves & their 5 year-old son (whom we are planning to ask to be
our ring-bearer). It would mean the world for both of us if they could
be there, but I know it's especially important for my fiancee, as his
family is small and currently the vast majority of guests on our list
are my family and friends. I do not know them well, so I can't feel out
the best way to broach the topic, and my fiancee is struggling with this
himself. Anyone with any advice?
