Well, there's no two ways about it...that sucks!
But, if someone doesn't want to be with you, then you don't want to be with them. I know that how she's landed will make you start to wonder & everything, but I think the best you can do is put it behind & move on. Yeah, that was really easy to type and reality isn't quite as easy to do, I'll definitely concede that.
You mention other things that are going wrong. Perhaps you can think of this as some sort of blessing in disguise. You can focus on those other matters without having to compromise anything you need to do because you have to consider your partner. Maybe, you can get the other matters sorted & then start looking for a partner again?
Just a thought. Good luck Mate.
