Thank you for proving my point! She had the choice, she chose him over marrying other men and having children (he told her everything, didn't he?), But the movie didn't give her that, give it him. The intention of the Russos, writers and Kevin Feige is to reward him. She is seen happily dancing, but all this is possible only because of him. And that her keeping him safe, haha, the role of a woman is not keeping man safe. Why can't it be the other way around? Mutual?
They would have each others back.
She said that in my opinion because every one sees Captain America. But she was able to see Steve. The small men who get into fights, who doesn't know how to talk to Women. She found in the bar after Bucky 'died'. Also she knew he carried the world on his shoulders. Captain America died, but only Peggy, Howard and the Howlies lost Steve.
The cap movies showed the relationship from Steve's view and the show showed Peggy's view.
I believe he would tell her everything. There isn't even a reason for not doing so. She would notice that he is different. Maybe he wouldn't tell every thing at all. May he needs time until he talks about a few things.
She had the choice letting him back in her life. Letting him in her house-her personal space/comfort zone.
