Remember one of y’all said that Tony might not have even told Rhodey what happened in Siberia so that’s why he was so cordial with Steve in IW?

Yeah, I haven’t been the same since the full realization that it’s probably true.

Tony suffers through things alone and doesn’t tell anyone, even his best friend for so many years.

He did it in IM2 & 3, even after Rhodey expresses concern & tells him he doesn’t have to go through stuff alone.

I don’t know if it’s that he thinks he would be a burden to Rhodey or that he really doesn’t deserve the concern or attention, but he just won’t tell him.

Rhodey has to find out or actually see for himself that something is going on.

It is realistic that Tony wouldn’t tell Rhodey about what happened in Siberia.

At that time, Rhodey had just suffered from his injury and Tony wouldn’t think to burden him with anything else and is more concerned about making Rhodey tech to make him as comfortable as possible.

I just can’t think of one opportunity that Tony would take to tell Rhodey about what happened. Not one.

And as a result, Rhodey would go completely unaware of the situation and treat Steve cordially. Maybe it wasn’t that he was ooc; he just didn’t know.
