I agree with KF that it the approach doesn't feel right to me. It's NEVER too late. The people you care about would rather you call the wedding off than make a massive mistake that you saw coming.
So I wanted to give you all an update on the whole situation. Also thank you all so much for your help and advice! It's truly meant the world. The week after Easter was my most manic. I had 4 random panic attacks during work. Never had one of those before and thought I was dying. Such fun. I went to pay the first deposit for legal stuff (yes I know everyone suggested against that, but I'm actually glad I did at this point). My payment was denied because it was a foreign transaction. Then I realized that the fiancé visa doesn't include the NHS. My daughter has epilepsy and HAS to remain on her medication. So I thought "well he could just come here and we could do a quick J.P. service and still have the actual wedding in September." Because it would be easier to just apply for the spouse visa and get healthcare right away. As soon as I mentioned this to him he got SO excited and I literally felt like I was going to vomit. I said I needed to talk to my parents to see what they thought. 2 days later, he's already got the time booked off work and was ready to get his plane tickets. I felt awful. Not excited. Brink of death awful. I wasn't sleeping, I was stressed and moody, and wracked with worry and fears. I did the math, all in total (visas, moving crate, plane tickets, and wedding) I would be spending $20,000. That would be nearly ALL of my retirement monies. And he was only contributing $2500. Coupled with the fears about my daughters health, is it the best thing for her, and for me, and then the fact that I'm a very faith-filled person and he is very not (in recent days it's become more of a concern than not that we don't believe the same thing)...
I spoke with a pastor friend and his wife. They suggested I ask for a postponement and then judge the response. They daughter had personal things going on in her life for a time and had broken up with her now husband when they were dating. When she did, his response was "you need to find out what's best for you. If us breaking up is what's best for you, then it's best for me too." I wasn't expecting that exact result but something similar since I'm the love of his life. We skyped on April 8th and I told him I needed to push things back a while. I needed to make absolutely sure that I was making the right decision as a mother for my daughter. There's just too much at stake for her. I wasn't breaking up, just pressing pause on our plans. The response I got was so beyond disappointing. He turned it all on himself, saying he'd already spent £1000 on the hotel and this was supposed to be his year to be happy after being sad and alone for so long, and what would everyone think. I said my parents have spent well over $2500 on my wedding dress and other clothes, I have 60 freaking whiskey glasses sitting in my dining room with our names on them, and if his friends can't understand that this is biggest decision I've ever had to make and I have to know it's right, then he needs new friends. My family and friends have all purchased flights and stuff as well.
Because of how he's handled everything, I have broken up with him. I've never been more disappointed in someone in my entire life. Shockingly, I'm really doing ok. I'm not panicky and weepy anymore. I've spoken to everyone in my family and my friends who've gotten flights. They are all happy that I've figured it all out before it's too late and no one is angry about the money spent. We're going to be enjoying a "dysfunctional family vacation" in September. The hotel can't refund the deposits but will be comping my room while we're there. The cake maker has agreed to significantly downsize the cake to a 1 tier and my deposit covers the whole new cake now. My daughter couldn't be happier that we're not moving. I was able to get 2 tickets with Virgin Atlantic for my daughter and I on the same flight as parents and in the same row as them for only $1106! I don't know how I managed that but everything is working out now.
If anyone on here is a Doctor Who fan, I do still have 60 whiskey glasses with a Tardis and love quote from the Doctor. As soon as I get the names and wedding date removed, they'll be up for sale.
if anyone's interested, let me know! They look like they'd be super cute juice glasses.
In all seriousness, thank you all so very much for your advice. You have all been amazing. If anyone is in Herefordshire in September, meet me for a drink!
