So... she has androphobia. Just like that or we will have some dramatic backstory? Sure hope so because that's just "eh?".
Also, there's no correlation with the fairy tale and what he is doing, in the story it's repetitive lies building up to loss of trust, not the them being a burden.
It would be better to say that his actions would have negative outcome, or worsen her phobia, like in the story but, whatever.
