Probably the only thing you can be absolutely, positively sure of at this point is that she will NOT be completely honest with you about anything.
You are new at this so your behaviors are understandable but I will re-iterate what others have been saying. Chill out and stop be so re-active. Try to operate from a place of power instead of fear. You have NOTHING to fear. The worst case scenario is what is happening so you cannot make things much worst. Get brave, try to do the right things. More than likely you can only improve on the sitch.
