Rejection and new model

Hi there,
I just realized that my anger towards my ex is mixed with feelings of rejection! Could you please check my IM and tell me whether this is the way to go and train my brain to think differently?

C- My ex left me
T- I am good enough (I think I used to think that I was not good enough)
F- acceptance and understanding for the divorce
A- be more kind when talking to him
R- more at peace with myself

Thank you
