I don’t know what to do

My boyfriend basically ghosted me a couple days ago after being together for 1 1/2 years. Pretty much everyone says to get over it but it’s not that easy. We would FaceTime for hours, even when he was working, everyday and saw each other almost every weekend. I was literally just with him and his family last week having lunch. I guess it’s something I said but I’ve apologized but got no response. I don’t have many friends or a social life so I don’t know what to do. This is supposed to be a happy time in my life, I just started my new career and thought I was in a happy relationship. How do you handle moving on after someone ghosts you?
