In all the time lines you had to step into mine

In his happiest time lines he had kids, a family. He was always torn from those too soon. The more he saw, felt, the more he hated his existence. The more world's where he was married, happy, he hated himself more and more. He didn't want to do this anymore.

Then there was that one timeline..... Asgard was not destroyed, Loki was king as Thor commanded so, stepping down to live a mortal existence. Thor found Tony in a bad state, his heart close to stopping. Thor took him to Loki, that was the story. When he woke Loki stared at him, eyes blinking, "Welcome back, thought we lost you." From there he stayed in Asgard, getting stronger, developing a bond with Loki. Only to be suddenly kicked out of Asgard by Loki. He never knew why, but here he was, with another Loki. He found himself falling into that ease of that old connection just to be reminded, he wasn't in the same head space. Of course this would end up the same.

The universe sure did love to torture him.
