Model regarding ex-husband

I am new to SCS and LOVE it! Thought work is fascinating and empowers me!

I want to let go of my irritation/anger about my ex’s current behavior (the same he demonstrated while we were married.) We see each other weekly because of the kids. I realize my feelings about his behavior are due to the thoughts I have about it. Can you please comment on my model? Thank you for your time.

C – I have an ex husband
T – His behavior has no effect on me
F – neutral, unhooked
A – I go about my life
R – I am not affected by his behavior.
