Has anyone you know died by suicide after a breakup like this?

So I knew a guy growing up who was infatuated with his girl at the time. But I never met her. Not to much longer later, I end up seeing him in jail. And he's showing every 1 a pic of his girl. But to his mistake, every 1 started giving him a hard time about it. I was still there when he got released and went home. He was so happy to be going home to her. Anyway, when I got out, I wanted to see how he was doing. Come to find out after he went home, found out his girl and his best friend were sleeping together. And he hung himself in the garage. Messed up. He was a really cool dude. But I thought about this for a long time trying to find out 'the why'.
But recently, I think I figured it out. I know he loved her. And he must've loved his friend too. Learning of them 2 closest people to him are sleeping together. He was so crushed... and wanted to hurt someone. But his love wouldn't let him hurt either 1 of them 2. and he can't live to see this going on, so he hurt himself instead.
I honestly won't every know what's true or not... but coming to this conclusion is through first hand experience. I'm recently single after 10 years. And honestly, ... I don't know... it fkn sucks. And life no longer makes sense. (sorry guys for expressing my thoughts.) I not looking for a answer or reply. Guess I just needed to vent. I have no one any more to talk to.
