Black Wido is (or was) with Winter Soldier.

Hawkeye currently is with Spider-Woman.

Sharon Carter (aka Agent 13) is the niece of Peggy Carter (you might know Peggy Carter from Captain America: The First Avenger, played by Hayley Atwell), or was... because Sharon died recently in the pages of Captain America.

So Captain America did have a love interest for a lot of years, but she's now dead, so Steve is currently in an angst stage of his love life.
