Ed thought of Winry.
When he was a child he thought of her as the kid next door. When he was and older boy he thought of her as the girl he was gonna marry. After he lost his limbs she was his angel, his savior.
For a while that was enough.
After Edward became a state alchemist, the thought of her helped him keep going. He dreamt of returning home whole again to get married to Winry.
And that thought was enough.
When Armstrong took them home to be repaired, Ed told Winry he loved her and they spent the night in each others arms, afraid to let go. Afraid they would never again have moments like this, never together again separated by the course of life...or death.
But for now it was enough.
From then on Ed thought of her as the love of his life and loved her with a fierce intensity, because he knew that at any time he could lose her, and since that was all he could do...it was enough.
He wrote her as often as possible (which wasn't very often) but in his letters there were no poetic declarations of undying love. Instead he penned in his dreams and fears, hopes and disappointments, that he loved her (and just that) that he saw now he always had, and that the thought of her was one of the few things keeping him going.
Letters were all they had, so it was enough.
Winry would cry every time his letters arrived, her heart aching for him and her mind fearing the worst. But she would write back with the same passion and realism, because they weren't the sort who lied. Fantasy wouldn't do either of them any good.
Ed thought of Winry as he died.
As he bled from the wound Envy gave him, Ed saw her before him and he remembered every detail, from her hair to her toes, and the love affair they had shared. He felt no fear or regret. His only wish was that he had been able to hold her, kiss her for one last time but, their love had been more than enough.
And when he gave himself so his brother could be reborn he knew Winry would take care of him. He almost doubted what he did but he had had enough time with the love of his life.
Winry remembered Ed.
She remembered the letters and the searing kisses. Sometimes she wondered if it had been enough. But she only doubted for seconds. Their time had ended, but they had been able to be together and it was enough. Even so she had to suppress tears every once in a while when she saw how unfair life had been.
Still their love had been enough, and just enough.
Sometimes though they both yearned and wished with all their hearts that they would have had more time, more than just enough. The desire would be so powerful they'd have to remind themselves that even if they wanted more, they had been able to have enough.
Just enough.
