When is the time to make new friends 😂😭

Of course there he goes liking another person 2 days after we break up

I can't even anymore. He breaks up with me for the stupidest reason ever which is he was bored of our relationship. 2 days later, today he posts on instagram like if you would date me. I commented really dude you break up with me then post this your messed up, sorry but its true. He deletes it. I'm just so fed up with him and saying things he doesn't mean or anything and my friends seem to like not notice me at all and not invole me in stuff. Just kill me. Anyone have advice for me?
