Time to move on

I (f21) met a man (m20) a few weeks after ending a one year relationship that wasn’t working out and this man was basically everything I wanted in someone. We dated for about a month with us both having the intentions of progressing to something serious and then he went completely ghost. About 2 months later, he pops out on social media with a girlfriend. I removed him on everything and blocked his number. This was all around February.

Yesterday, me and my friends decided we would burn all of our photos and memories of our past exes and situations. Then, later at work, he walks in with his girlfriend, this was the first time I’ve seen him since he went ghost. I nearly broke apart at work, he never came up to me but I believe he did spot me as he walked out not long after walking in. He did know where I worked but I think he was hoping that I would be at home for the summer or that I wouldn’t be working. I don’t know how to feel right now but all I can do is cry. However, I think this may have been the closure I needed.
