No I've heard all about ad nauseam and he dumped her months ago, she kept texting him until he fucked her again the other week after refusing to see her for months and the delusional psycho thinks they are together.

That's not a relationship, that is some guy you fucked and who dumped you and you don't get it, if he wanted to be with you he would be but even after months of you texting him the best he could muster for you was one more fuck.

Have you ever even had an actual relationship? It involves the other person wanting to be with you and you both actually being together. Not some guy who dumped an insane skank he fucked.
