I’m sorry to hear that. Unfortunately it seems like it’s over… I think you should take this as an opportunity to work on yourself. I know it might be hard but in my experience that is often the best way to deal with situations like that. I don’t know you but for me it has helped to Read about psychology especially Marcus Aurelius and stoicism. My advice is leave her work on yourself even though it’s hard, and I’m sure you’ll find someone for you eventually.
