Their relationship was perfect. Clark was caring, sweet, kind, loving, considerate - all the ideal qualities in a man. Dima tried to keep up with the him and not lag behind. He cooked dinner when Clark returned after a hard day, gave him a massage, was affectionate - Dima thought that he lived up to the standards.
But apparently not. Clark started coming home later. He often didn't come home at night. Dima knew Clark wasn't that kind of person, he wouldn't cheat, but he was becoming distant. And what hurt the most? Dima knew why. He knew who Clark went to. Who he spent his evenings with. Who he often "partnered" with on missions. Batman. Of course.
Clark became more and more distant, and Dima couldn't do anything about it. Because he can never compare to Batman. Clark didn't stop being affectionate or caring, but... His kisses became less frequent and shorter. At night he slept with his back to Dima. It was a light, imperceptible cold. But it was there.
