Now that is a deep interpretation. She wanted to be lured. She wanted the romance.
But...if she deleted the wife first, then proceeded, then who's the adulteress and who's the mistress?
She's still getting romantic poetry from a (theoretically) married man.
I read about this same thing in some articles about this episode. Some called Janeway a cheater.
These are some pretty interesting insights from the woman's (Janeway and the female fans) point of view when it comes to this topic.
