Hearing she was pregnant, it almost felt like someone had torn out his heart. He never had feelings for her other than that as a friend. He saw her smile when she said the words too, and the way she looked at Will. Why did all of these things bother him? Maybe it was because he hid his feelings for her even from himself. It didn't matter now anyways, it was too late. Whatever might have been, or could have been that all went away now, because he was to afraid of himself. He walked away feeling these feelings of hurt he never felt before. He knew he had to let her go and be happy with Will. He just wished he had known so he could find the right words to say to her. Right now, in the middle of this case it wasnt the time.
"Hotch, wait!", she called after him
He couldn't help it he turned around and said the first thing that came to his mind. "JJ you could have told me" he knew that he could hear the hurt in his voice but at this point he didn't care. He walked away from her thinking of all the conversations they had, her helping him with the loss of Haley, and her confiding in Him about her sister. The feelings he had for her were love, and he only wished he had realized sooner so he could have told her.
