When Bucky realized he’d need help after escaping from Hydra after the helicarriers fell, he returned to New York. The Avengers helped him get better, and he was doing well enough, but there were still things that were difficult, among them his relationship with Steve.
There were things he felt he had to hide, and he tried to keep them from interfering, but they only ended up driving a wedge into their relationship, and what was worse, he didn’t realize how bad it was until Steve was already leaving, getting on his bike and heading out to find his own peace.
