Bucky had been in a relationship with you for a while, and you both had developed a deep connection.

His happiness, his smiles and the shine of love in his blue eyes was just in your presence.

You're his everything.

However, Bucky had recently discovered that you intended to leave with Steve using the Time-Space GPS of Bruce Bannr to go back in time.

Steve wanted to go back for Peggy.

And you wanted to go back to your parents and see what happened to them in 70 years.

Maybe even living with them the rest of your life.

Bucky was left feeling not worthy of staying with you, as he struggled with his own self-doubt and insecurities.

He questioned his worthiness to have a relationship with someone as beautiful and kind as you.

After all those lovely promises, you'll be gone too just like his bestfriend.

As you finalized your plans to leave, he wrestled with his conflicting emotions.

He longed to be with you, but his insecurity held him back.

He know he can't go with you, in the past he was nothing but the Winter Soldier and he doesn't want to try that feeling again.

Sam Wilson was standing there, watching the depression lover of you saying goodbye to you with Steve.

"It's going to be alright Buck" Steve comforted him gently as hugging him tightly.

During the hug between them, you noticed his eyes filled with tears while looking at you.

A silent plea for you to change your mind, he couldn't handle losing two important people in his life in one time.
