TT kills, knightsbff. KILLS.
I can hear based on this post that you have an awareness of this.
Don't just feel strongly about the timeline, feel completely about it.
Something Crazz and I have in place when he kneejerk lies (a lot of the time I can tell) is that he has a "take a breath" grace period to retract and replace what he just said with the truth.
Awareness of his lying mechanism and intent to get rid of it is one step, but having something in place to correct the behavior is just as important.
I have a hunch you're hanging onto more than a few details. The fact that you feel that a timeline would be revealing kinda points to that.
It's scary. As a BS 2.5 years out I have compassion for that.
You want an authentic life with knight? You want to never surprise attack him with details?
Exorcise alllllll the demons. Little ones, big ones, awful ones... oh and those "not really a big deal" ones? Those too.
It will hurt, but it will free you both.
All the truth out = no new lies/hurts.
You can do it.
