That's not true.
Cap was dating Sharon, but Peggy, the newly out of decades of being in a comatose state- was infatuated with Steve and was under the impression that she and Cap were still an item. Cap was very uncomfortable about it, but didn't correct her out of awkwardness/not wanting to hurt her just after she'd recovered.
Sharon, however, thought the whole thing was funny. That
was douchey, but alas, that was the seventies.
