I feel that is one of the top songs to describe Dean, or at least a song that describes one aspect of him.

I am insensitive, I have a tendency

To pay more attention to the things that I need

Sometimes I drink too much, sometimes I test your trust,

Sometimes I don't know why you're staying with me

I'm hard to love, hard to love,

No, I don't make it easy,

I couldn't do it if I stood where you stood,

I'm hard to love, hard to love,

You say that you need me,

I don't deserve it but I love that you love me, good.

Love me, good.

Girl, you've given me a million second chances

And I don't ever wanna take you for granted,

I'm just a man, I'm just a man

Lee Brice "Hard to Love"

After an hour she opened the bathroom door. "Feeling better?" Dean asked. She nodded and curled into his side. He wrapped an arm around her waist and pulled her closer. She was exhausted, and now that she was safe, a light sleep came fairly easily. Dean tucked the comforter tighter around them. Then he settled down. The shifter had been with them for nearly three days and they had not noticed. How could he have been so oblivious? The devil was in the details: her personality; her carelessness with small things; the lack of a ring because of the silver band; the thing with Sam. He looked at Sam's sleeping form in the other bed. When he walked in and saw that…he had believed it was real. The feeling of his heart cracking in two was not something he could easily forget. He knew that she would never do something like that, but the certainty still did not stop doubts from skirting into his mind. What did she see in him, anyways? He was rough and cursed like a sailor; he drank too much; he was shattered and held together by glue. She was his glue. Sam had his deltas, too, but he was better in more ways. She deserved somebody better than Dean. He didn't understand why she had chosen to stay even after experiencing all the worst parts of him. But he was grateful she did. Most of it was probably blind luck on his part.

He kissed the top of her head. "Goodnight, Abigail. I love you."
