Also asked, will Sam and Bucky get together?
The rumor has never been officially debunked. That is, both characters are yet to enter any kind of romantic relationship with anyone else in the MCU. However, Mackie has stated many times in the past that he hoped his character would end up with Scarlett Johannson's Natasha Romanoff AKA Black Widow.
Secondly, does Bucky Barnes have a love interest? Bucky Barnes' love interests are few and far between in both the MCU and the comic book pages. One of the few serious relationships that Bucky built outside of the MCU was with his love interest Natasha Romanoff. The two had a fascinating partnership, as Barnes was initially her trainer in the Red Room.
Beside above, who does Bucky Barnes marry?
Surviving the war and believing Rogers had died during his last mission, Bucky eventually married Rogers' fiance Gail and had a huge extended family.
Is Bucky in love with Steve?
While hero-and-sidekick relationships in comics have been interpreted as having a homoerotic subtext, in Marvel canon, the relationship between Rogers and Barnes is strictly platonic, and is not depicted as sexual or romantic.
