Bucky always backed down while you were dating Steve. Steve was his best friend and he wanted him happy, but his feelings for you only grew.

Bucky has liked you since the two of you met.

He's never dated since the 1940s. When he escaped from Hydra and somewhat healed from the trauma then joined the Avengers, he liked you right away.

He wanted to back off when you dated Steve, but as he was arguing with you in the kitchen of the compound while everyone was on a mission, he couldn't hold it.

"Do you think of me when you're with Steve? When you're in bed with him do you think of me? Do you really want him?" The words spilled out so fast in the small fight you were having.

He stepped forward, causing you to back into the kitchen counter.
