Just need to vent a little!

My FH asked his uncle for addresses for 9 family members (these include the uncle’s children). Of the 9 he gave us we find out after invitations have been mailed that 7 are wrong! Invites were mailed prior to Christmas and at this time only one incorrect one has been returned to sender. We have since found out the six old addresses no longer have forwarding to their new addresses and none of them have come back (this will only happen if the new house owners put the invites return to sender). Which at this time is doubtful. I created and wrote each invitation myself , I’m not even sure I have six left to use! Just frustrated. We have received 1/3 of our rsvps already and of those only 3 are from FH’s side. This is why I personally asked everyone from my side for their addresses! Vent over.
