So let me get this right in my mind. Connie keeps secrets from you, and Patrick (are these especially dangerous secrets? Sometimes people keep secrets). You ...said what exactly, that you wanted her to be more forthcoming? That you and Pat wanted her to be more forthcoming?
And she got angry. What did she get angry about? Was it actually about you or about Patrick? And now she's on a kick of believing you think she's a terrible person (is this because of keeping secrets from you, or from Patrick?) and yet believes that you accept her despite her faults.
Where did the kissing fit into all of this?
And does she actually have anything into which it might be possible to interpret all manner of ills? Why on earth did you front up her issues with her brother?
