inner turmoil

so I am sitting at home feeling shitty about my ex, who after 14 yrs of knowing each other and dating for a year ghosted me. he was the first guy and only guy I was ever intimate with. he totally disappeared without saying a word, the last time we were together things were great and now I am clueless. it sucks because I thought I knew him and that we were in it for the long haul. I am totally heartbroken, I want to cry but I don't want to cry over him. I don't want to be sad over someone who could do that to me.
