We were pretty serious and had been together for four and half years.
Since I had to move back to my country and I was going to come back to the state to live at some point , he let me leave my stuff at his place. I emailed him if he still have my stuff and if he could mail them to me... but he doesn't respond. I emailed him again a month later. He still doesn't respond. Should I just assume that he doesn't have my stuff anymore?
