Db grew up being very close to each other. Over the years our lives have taken very different paths -he has a very successful high earning job and I am a sahm. I have tried to keep up a relationship with him- invite him to my kids birthday parties, school plays etc. today I called himad in am concerned about our mum. She is under alot of pressure looking after her own mum. I raised my concerns but he threw it back in my face saying I give her extra demands as she does help with my kids but I don't think too much and she offers rather than I ask her. He then went to say he thinks its strange i expect him to go to my kids parties etc. this has really hurt me as I don't want him to feel obliged just thought it would nice to have a relationship with my kids. He said its too much and he doesn't know anyone with this relationship with family. I have never once in 10 years asked him to babysit etc. aibu?
