I'm 13 and last year I dates this guy for awhile and then we broke up an he was so upset that he didn't talk to me then a few weeks ago I tried texting him once just saying hi and he randomly comes up with all this crap saying you are a stalker or you are obsessed and I ignore that then later I say hi again and he talks for awhile but ( not a nice good way) then he is like you are a stalker an I'm like how and he said u won't leave me alone and so I say OK I'll leave u alone Ig and he is like JOY! Then a few days later I ask him if he even remembers us dating last year and he says no and idc and I'm like we did though and I care and he says well I don't. So what should I do with that?

You should move on and never talk to your exes again, why does it matter what he thinks or remembers?

You didn't make it clear who ended your friendship (if he was upset and wouldn't talk to you because you broke things off or he broke things off himself)... that means; continue to exit gracefully. Leave them alone. When they make it clear they don't want to remember you --- move on as you should in the first place.

He broke up with me and a few weeks ago I asks if we could be friends an he said no because I don't know u! And that made me feel stupid when he said that
