How do you move on?

How do you move on after a breakup?

I've dated before but she was the only one I've instantly felt a connection to so fast that I'd considered her my soulmate for lack of a better term. She broke up with me while saying the relationship was good and she loved me buy didn't want to wait until things got bad (idk why they would get bad) she stayed over that night and cried saying she didn't want to do this?

We had been together 1.5years and I've never experienced love like it and I know she felt the same probably even upto the split, I think the honeymoon period had ended for her and she read that change as a need to split.

I had a engagement ring all sat waiting until our trip to Japan or 2nd anniversary whichever came first.

I have people I find attractive in my DM's but I can't even entertain the possibility of dating as I feel like that's it for me it's over, she's all I could have ever wanted and all I still want. It took me 32 years to find someone I fell truly in love with and I can't see finding something like that ever again.

It ended in June this year and I've become so much stronger and more confident having time out of a relationship to work on myself but there is still a massive hole where my heart was and I don't know how to fix this.

I have no irl friends here to fall back on either, everyone I know lives 100's of miles away, I'm so alone.
