I always use the "mid-life crisis" as the excuse. It's great fun on the boards to get the C/7ers all riled up. LOL. But it's not what I really believe would work well in a story.

I could see him just giving Janeway a simple goodbye kiss and being blown away by the chemistry, so much so it would be impossible to ignore. Oh boy. Don't get me started!
