How will I ever move on

My partner (26F) is struggling at the thought of doing 9 months long distance with me (24M). She’s genuinely the most special person I’ve ever met and I don’t want anything in life other than to be with her. Everything was going so well, but the closer we got to me leaving the more and more she struggled at the thought of it all.

It’s been 3 weeks since she wanted space to figure things out. I’ve cried every day. I can’t sleep anymore. My life is falling apart. The worst part is having to stay silent and not text her constantly while she has time to process things. As stupid as it sounds, I don’t think I can ever love again if she ends it. Things were perfect, I never saw this coming.
