Weddingbee boards

I'm having some trouble figuring out what to do about this situation!  My FI asked one of his friends that lives in Florida to be a GM back in November and he said yes.  Well during this year him and his wife have split up and there is a kid involved.  So he is going through a lot, but my FI has tried to get a hold of him since the end of May and he isn't answering the phone or returning his calls or texts.  FI has tried every month since and has spoken to ex co-workers to see if he is doing all right and if he is still around.  He is, but will not get back to FI.  Problem is that I already bought him his plane ticket to KS and he did agree to be a GM, but I don't know what to do.  We are going to be needing to get measurements the end of August and I really want to get my programs printed, but we are still waiting to see if he pops back up.  I just sent his invitation in the mail with a note saying we were needing to know, but should I just give up on him and assume he won't be here.  I'm afraid if I do that then he may show up!  My FI is really upset with the fact that he won't even return calls and such, but is even more upset because he misses his friend and I know it would mean alot for him to be in our wedding.  I guess I'll just wait a little longer and hope that he gets in touch with him in the next few weeks!!

Thanks ladies for all the great advice!  We actually won't need to get a backup or stand in if he doesn't get back to us, because I only have 2 girls standing up with me and FI was having 3, so if we don't hear from him it won't mess things up that way!  I'm just more upset that he hasn't called FI back!!  Our main concern of course is that he is doing okay.  FI has said to assume he isn't coming, but I'm still holding out for him!!  Thanks again ladies!!
