He has always loved her. There are subtle hints throughout all 3 seasons. He just didn't realize it until the kiss.
The kiss was basically a catalyst for him.

If you noticed in Colin's journal he talks about his intimate encounters but always ends with how alone and distant he feels. He is lonely and looking for an emotional connection. Look at his face after he and Pen had that kiss....there is something there that wasn't there before for him.
