I put this in teenagers but I'm reposting it here because DP and I will be talking to granny in a minute and I really do want to know if I'm on the right track.
I've posted before about our situation. We've taken over care of DN (DP's son) who has been brought up by his granny after both his parents died when he was a baby. Granny is easily manipulated by DN and constantly interferes in our relationship, creating a sort of triangle which is very irritating.
DN is with granny for a few days at the moment and comes back to start term next week. He has a target setting day which is for children and parents to attend. He has got granny to ring DP today to say he doesn't want us both to go as it would be "too overwhelming" so he just wants to go with DP. This is not surprising, he grew up with DP and I'm just a nag . Our relationship is progressing ok, but we have ups and downs.
DN is a bit off me at the moment, due to some well-deserved but very fairly given tellings off. He has been with granny on and off all holiday and comes back being very rude, refusing to do the usual stuff like putting his plate in the dishwasher, saying thank you.
I am responsible for his homework and all dealings with the school. It's me they call.
I understand that he doesn't want me to go, and that he loves DP much more than me, but I can't have him telling granny telling us what to do.
DP has called her back and left a message to call us. He agreed over the phone without thinking but is of the same mind as me.
I don't know whether to leave it for this time with firm boundaries for this stuff in the future or stand my ground.
