The backstory to the relationship stuff is here:

We are due to be going on holiday on Monday for a week. Right now, I really don't want to go. I don't even think I want us to be together. He has paid for the whole holiday to celebrate my birthday later in the year, so if I pull out/we have to cancel, he loses about £1000. I would offer to pay some of this, or I guess he could go by himself. But I do feel guilty that he has arranged and booked and paid for this holiday, and I now don't want to go.
Do I just end it, not go, and stop feeling guilty? Or go, even if I don't want to?
