How to deal with the fact that my ex will be with someone else? How do I move past on when I was the one that got abused emotionally, when I was the one that got mentally sick and scared because of her.

I know it sounds a bit werid, but I really need someone to talk or some advice. I'm so deeply depressed because of her, I need someone to tell me that it's okay. I had this dream that my ex was with someone else and it continues to bother me every second.

I sent her a message saying that I missed her but I don't expect her to come back and that I didn't want us to leave on bad terms, which was probably stupid for me to do.

I just need to get over her, I've been making progress, I got a good job, been writing articles, engaging with friends a lot more. I still can't get over the fact that I put so much fucking effort into that relationship and it's all gone to waste and that some other guy will take credit and get her without no effort at all. She literally left me because I wasn't close to her, and she said that she needed someone close.

I'm just lost for words at this point, I really really need to move on but I don't know how.
