I'm hoping that you're just getting worried as your wedding is soon.
I've been there and now I'm single, not saying that would happen to you, but you must take a step back, give her time and space, in the end I had to imagine cuddling up in my head.
She pushed me away and now we're apart from each other, I (like to think that I) was the best thing in her life and now who knows what's going on in her mind.
She pushed me away a few times and we made up again, but now we're not together and there is nothing I can do or say to make it better, it's under her control.
