to think I'm their bloody aunt?

[MsScarlettInTheLibrary]

My partner and I have been together 10 years. Committed, but unmarried. Unlikely to marry. Don't wish to marry. We have a daughter of 4.5 years.

Partner's sister and her husband have together 8 years, married for 5. It's the second marriage for each party. They have a son of 2 years and newborn daughter.

We are very friendly and see each other at least once a week. We babysit for each other and our daughter calls them Aunty X and Uncle Z. I love my niece and nephew very much.

Their son is beginning to talk. He has been instructed to call us Uncle A and First Name. I am apparently 'not really an Aunty' because I am 'only a girlfriend'.

I'm hurt, to be honest. AIBU to think their children should call me Aunty Scarlett and not just Scarlett? We're the only unmarried partnership in the whole extended family and sometimes just feel so bloody misunderstood.

can't beleive I am arguing this as I really don't give a flying fish what the Op is called by her partners neices and nephews.

technically my father is my DS's grandfather but given that he has never met him I would rather poke my eyes out with a spoon than refer to him as such.

Very nasty of your dp's family. A very obvious put-down. Start referring to them by first names in front of your dd and see how they like it - because if you are a semi-detached member of the family, presumably that extends to your daughter? None of their damn business whether you want to get married or not. Aunt is often used for family friends, ffs, it's not a special title awarded onto to the lucky few who tick every box on a 52 page form!
