There are certain questions that signals that something is going wrong in your relationship.
* But we are friends, aren't we?
If you got to the point of playing the "friendship" card this means you are not friends and one of you is trying to either set boundaries or claim rights.
* you love me, don't you?
If you feel like asking someone whether or not they love you, this might mean they don't.
* but you couldn't be possibly betraying me, no?
Chances are you have been betrayed and in denial.
