My Boyfriend Lied

C: my boyfriend lied when I asked him if he had just smoked pot
T: my boyfriend hides things from me, what else is he hiding, he’s not having fun with me while sober, he’s self-medicating/bufferibg because he’s more unhappy in life than he’s letting on, he doesn’t trust me enough to tell me the truth
F: betrayed, scared that this is a red flag, insulted that he thinks I’m that stupid to believe an obvious lie
A: I shut down when we try to talk about it, lots of black and white thinking
R: we grow further apart

So that’s my model from tonight.

Is my circumstance line right? And if it is, how is a lie neutral?
