I need to vent about a family member who is manipulative and toxic and recently betrayed my trust and privacy
Did they intentionally betray your trust?
I think it was a mistake, but it hurt my feelings anyway.
Even though it was an accident you can still feel angry about what happen. Let the person know how you feel so you don't let the feelings linger.
I'm not mad. I'm going to manipulate my way into getting what I want out of them.
Well I don't think you should be trying to manipulate them, I just think you should vent and get your frustrations out.
