I Accept Responsibility For My Own Actions

For the good and bad!
I am pouting, hurting, madder than hell about a secret my mother and son had.
I learned after the fact.
sigh...
My mother lives 9 hours away from me.
My son lives 22 hours away. I have not seen him in 5 years!
The secret was my son came to my mother's, he is her executor and came to settle her affairs.
NO, she is not in bad health.
Neither one of them told me he was flying in for a weekend.
How I found out was my mother sent me pictures of him at her home!!!!!!!!!
I have been carrying this anger for months now.
I finally wrote them both and told them how hurt I was.
Now... I have shut them out till I cool down.
This matter is with me every day.
I have to let go!!!!
Edit... I drive to see my mother twice a year... three times would not have matter in the lest!!
