My father passed away three weeks ago. Every holiday, bday,etc my in laws and Dad have spent together because of grandchildren. The day before my Dad's service my MIL spent day at amusement park with brother in laws family. She was "too tired" to attend funeral. I was so upset. Can't believe she couldn't come and sit in a chair to be there for me and her three grandchildren. I guess I know my position in this family but I cannot let go of this anger. My husband is also upset but has been to visit them. I have kept my distance. How do I get over this and move on?
