Batman wasn't selfish. When he stepped out into the inky nights that terrorized Gotham, he put his life on the line to restore hope and keep the people of Gotham safe. He was justice, a firm defender and enforcer all at once. He didn't need others, didn't need to love and live like a regular civilian. His purpose was to protect Gotham from himself, everything else came second in his list of ever growing priorities.
But Bruce Wayne? Bruce Wayne was undeniably selfish. Bruce Wayne knew no boundaries when he wanted something completed or attainted. For all the good he did in the world, all the donations and charities, he just couldn’t curb the part of him that longed to live in his desires. For a man that had so much wealth, perhaps it was almost in his nature to just be a bit greedy.
That's why you still remained present his life, when nearly no one else did. You, so patient and sweet, sometimes his only bright ray in a city of crime and bloodshed. He had tried to push you away at first, one part of him scared for your safety and the other scared of him being vulnerable.
That didn't last long.
Bruce's chin gently nudged yours up so he could pepper the column of your throat with the most gentle of kisses. His eyes slowly fell shut as his body completely melted into yours while also being careful not to crush you with his weight. Hands that had been violence, bloodshed, death, cupped your cheeks as if he was holding the most fragile, precious treasure he would ever come across. "You're staying the night, right? Just move in with me already, I'll send Alfred to get your stuff."
It wasn't a demand, Bruce could never imagine demanding anything from you. Although he never imagined being so clingy and vulnerable with someone either, so who knows. He was surprisingly the pursuer, wanting to move fast and get as much of you in the daytime that he possibly could. It was dangerous to be with Batman, but he reasoned that you would be much safer in a place he could keep an eye on you, somewhere with amazing security and a unassuming butler.
He could almost convince himself that your safety was the only reason he was desperate to keep you close.
Almost.
"I don't mind your pet or anything like that, if that's what's holding you back from moving in. Alfred is good with them, and I can get along with it." It. God he was just spewing things at this point, desperate to get his point across. How could the greatest detective in the world not understand his partner? It was maddening, you were maddening.
In all the best ways.
