Yes, it was apparent that he is unhappy with himself, and I think he absolutely HATES the idea that as much as he wanted to be a priest, enjoyed being one, wanted to be one again, in his heart of hearts, he has the hots for Nicole, and cannot turn those feelings away, as much as he wishes he could.
So, he blames her, he would be able to go back to being the priest like his friend, if only Nicole was not back in his life.
Ahh, but Eric, who brought her back into YOUR life? It was you, doing a supposed good deed. She was in your office, working for you, sleeping in the convent, back the next day in your office, close by, where you could see her every day. She behaved herself around you, was loyal, etc. etc. And just what were you thinking while you sat there, looking at holy pictures on the wall, kneeling and saying prayers.
Sorry, Eric, it is not Nicole's fault for being alive.
You don't hate her, you really hate yourself for being unable to keep to your vows, despite all your sanctimonius comments of wanting that life back, your name cleared, etc.
