Good choice... let her squirm... the less she knows the better.
She likely wants the same as your H... INTEL
The cat and mouse game is now reversed... lock up your pc... I can almost guarantee your H is going to try to get into that sometime soon...
You are the mouse now and they are panicking and going to chase you about for a while... You need to protect yourself... you are pretty vulnerable while you share the house with him... don't leave ANYTHING out that you don't want him rummaging into...
