Definately take a deep breath! It's going to be alright. I felt the same way too. While I loved my wedding and was happy to have everyone there, it wasn't my dream wedding by far. If our families would have been alright with it, we would have
had a small wedding (less than 20 people) over looking the beach or Lake Tahoe. Neither of us wanted a big wedding, and it turned into something that we completely compromised on with our families.
Paddy might be on to something. Does your FI need some you to get things started for him? My DH was pretty useless in the planning process. I learned early on that if I wanted his input, I needed to keep it very simple and give him 2 or 3
options. There was no way he would have been able to pick a photographer without me showing him where to look first. And then he would have procrastinated until it was too late simply because there would have been WAY too many options for him. But I knew
this when we got started and I was happy with planning the wedding around him.
You definately need to sit down with your FI and lay it all out. Make him understand that you're only having "this" wedding to make his family happy and he needs to participate too. Especially since you don't know Houston and most of the guests
are HIS friends and family. Let him know your feelings about giving up going back home. Make sure he knows how frustrating this is for you. He needs to step it up and contribute! If he still doesn't get it, then I'd take that $5k and get married in
Hawaii just the two of you. ;-)
Good luck and know that you're not alone on this one.
