He got married...how am I supposed to keep going?

It's been 8 months since he discarded and ghosted me after 10 years together and I'm still completely in shambles. He got married today to some girl in Nepal he just met last year who he barely knows and I saw the wedding photos.

He ignored all of my pleas for closure and discarded me over text. Every attempt I made to reach out he blocked. He abandoned me in my darkest hour with no support system when all i had was him. I don't think I will ever move on and I'm compeletey traumatized and heartbroken from all of the emotional abuse and the future I thought we would have. I have severe depression and have been very suicidal. Why did he refuse to give me any closure? How am I supposed to recover from this?
