I can’t get over my ex

My ex and I broke up three months ago and I can’t get over him no matter what I do. It wasn’t a particularly long, we were together for two months, but we knew each other from before, and it as a really intense relationship, also we didn’t broke up because we weren’t compatible, but because I moved out of the country; after we broke up we kept talking and promising stuff and it made it harder, and at the end I was practically begging him to fight for us and he said he didn’t want to be with me anymore.

I keep having this dreams about him, and hoping that we talk and just... I don’t know. I just want this to be over and not feel like this anymore.
