Hi Girls,
We've been having trouble deciding how to word our invitations.  We're paying for the majority of our wedding but my parents are paying for close to half.  If we use the following, then it looks like my parents are paying for the whole thing.
Mr. and Mrs.
request the honor of your presence of the marriage of their daughter
me 
to 
FI
son of ...
I don't want to use, "together with their parents", because the future in-laws are not helping with the wedding, they're hosting our rehearsal dinner so those invites will indicate that.
Is it tacky to do 
Mr. and Mrs.
together with their daughter and future son-in-law
me 
and 
FI
son of...
And do we even need to put his parent's name on the invite with the "son of"
Any suggestions would be greatly appreciated.
Thank you!!
