<human>: I met a guy last summer and we bonded really quick. I had recently gotten out of a relationship and we went on two dates. On the second date, he showed me that he left me in his contacts as "girl who will be my future wife." Sweet, but hella early. 

He invites me to his going away party since he's going to work in a different city. I attended the party, but things get sketchy after I left. On his snapchat story, one of his friends is posting about how he's hooking up with different girls. We were never official so I no longer take him seriously. The story was deleted by the morning, and I never found out if what happened was true or not. 

Later on I'm dating someone else and he asks me to come visit, but I turn him down as I'm no longer single. We stop talking for a few months then he starts messaging me again. He lets me know that it felt like I was stolen away because he thought I was his girlfriend even though he never explicitly told me or went out of his way to show me that he was serious. He goes to the beach everyday. The sand no longer reminds him of me. He tries to lure me back with a tea place I might be interested in. He wants me to be with him until he leaves the state for school. It's strange that he would come back and say all this when he can just hang out with anyone else who is closer in distance. 

Now it just feels like I'm hurting myself lingering in the past thinking about what if's. It doesn't help seeing things on social media of him with other girls. I recently unfollowed him on instagram, and maybe I should remove him from all social media.

Can you give me a shortened version of the text?
<bot>: An ex-flame came back to me claiming that I was his GF despite never confirming any relationship status. Should I remove him from all social media and move on?
