You two got into a bad argument. It turned out for you to yell at him for something he has done.

Now he's looking at the floor while standing looking away from you and not talking.

He felt you angrily tug at his hair and that's when he snaps at you so much you almost fall on your butt but he catches you.

"I'm sorry." He had a muffled voice as he hid his head in your neck. You started to hear sniffles "I-i didn't mean to hurt you."

Was this little big baby crying?
