He wasn't -- it wasn't a planned way to make Steve worry about the state of both of them, but surely he had to be aware by now that Tony, with all his manic and nervous anxiety, wasn't the sort to ever sit still, particularly now when he was given something difficult to mull over. But even in the every day moments, he was just as articulate with his hands as he was his words. It just was what it was.
So he paced.
"The timing is bad," he said, a little sardonically. "You couldn't have done it, I don't know, directly before you slept with me?"
Maybe it shouldn't have bothered him. It wasn't like Tony was innocent in love by any means. He'd done things in the past. Terrible things, really. But none of those people counted. Not like Steve did.
He stopped in his pacing, hands at his sides and just looked at Steve for a long moment. "Would it be different? If he wasn't in love with someone else?" Which, actually, he made a note to talk to Natasha about because wasn't that wild. "I'm not -- I'm not accusing you of anything. I just. I'm not good at being happy either, Steve." But he wanted to be better at it, and he needed to know if this was something that was actually going to allow for that. Jesus fucking Christ, he wanted it to be so badly. Tony didn't think he was wrong in being wary - he so often felt like when he went for the things that he wanted the most desperately, that was when things really started going sideways.
