Yep. If in the absence of some compelling reason, you're suspicious or paranoid enough to be eavesdropping, not much good is going to happen next.Eavesdropping or spying virtually ALWAYs ends up with a destroyed relationship. You start hearing things out of context and interpreting them inaccurately, and you become paranoid and mistrustful.
Next thing that happens is you start to harbor resentments for things you've heard (and are interpreting in the worst possible light), which affects how you relate to her. She picks up on your attitude, and the downward spiral has begun.
It's best to use other means to deduce what's going on with her. Spying will surely destroy things, and it will be a slow, painful death of the relationship.
