Hi, my friend asked me to post this as she's not on here but would like some opinions/ideas of what to say and do.
DF got married 5 years ago and DH was a big part of her DD life as they all lived together. He left her a year ago and moved out but has continued to see DD13 regularly.
He has been massively overstepping and is getting worse. She doesn't want to cut him out of DD life but he has kicked off because DF took DD to a close family members funeral and due to distance ended up staying 4 days and he said he was told 2 and no one had the courtesy to tell him and he really wasn't happy. DD real dad has taken her out of school for a couple of days this week to go on holiday and due to strikes she is not missing a lot of time off school. He has kicked off again and has text the dad and asked him to change the date of the holiday and said he's not happy! He is demanding to go to parents evening and options etc, has put his name down as a point of contact for school and wants every update as if he is her dad. She needs to tell him he is massively overstepping boundaries but he seems to think he has full parental rights and won't take it easily.
