SIL is an incredibly selfish person, emotionally unstable and inmature, with a drink and an attitude problem, but nevertheless she is ds's only aunt. We used to be friends a few years ago, then moved away and things went bad, she didn't talk to dh for about 2 years and now they talk about once a year only. DS was born 8 months ago, and she has not yet met him, I find this astonishing, she's sent a card, that's it.
I feel that she needs someone to tell her something, not sure what (actually when i think about it I feel rather more violent than just talking, but I'll keep that to myself). AIBU in wanting to write to her telling her that she's missing ds's babyhood? And if you don't think so, do I have to tell dh that I'm writing to her? I suspect he'll say I shouldn't write to her.
