How do y'all get over a heartbreak

So like, as y’all know, I proposed to my crush and wanted to get their attention, so I dumped ALL my intrusive thoughts in one post about how down bad I am for them. But plot twist… they have a wife (who also flirts with others btw),and they don’t want me not even a little.

AND....get this,they think I’m an alt account of someone they know which is also false I kept trying to talk to them, at least as a friend, but bro… useless. I don’t know what to do anymore, I literally can’t control how I feel I just wish they’d even talk to me, even if it’s just cussing me out (is it obvious I’m a masochist…? NOW WHO SAID THAT).

I even stopped screaming because they told me to also i changed my username because their wife said so,What did I do, my love,my glorious queen? Are you seeing this? I’m dying to get any attention from you. Like, why is literally everyone else telling me to shut the fuck up while you just… ignore me ☹

Tell me guys what should i do cause i legit feel so heartbroken and depressed rn and i am deadass,i think I'd be happy even by them talking to me a little or even cussing me out idc i am just so desparate
