Sorry if 20 nearly 21 is too old for this forum but hopefully someone can help me - my 20 yr old DD is very isolated has no friends, as she has fallen out and moved away from everyone who has known her - she quit uni and came home and has no contact with anyone other tham a BF
She works and pays us some rent and we bought her a car to help get her going in working life.
She is often rude to her Dad and sister and she has massive rows with her BF when he is here, with her often unreasonable behaviour and he has left her 3 times and they keep making another go of it he is very welcome here and she treats him badly.
Last week she was being a bit off and rude about her Dad whilst having evening meal criticising him for how he was eating and I told her that he can eat how he wishes - she then became grumpy and finished her meal left the table her younger sister said ‘ you never say thank you for your food to Mum ‘ she mutter I did say thank you - she never does - and maybe on this occasion she did younger sister always says thank you for tea and she hates how her sister isn’t polite or being appreciative to meals being cooked everyday for them.
I sent eldest DD a message saying I don’t like her being critical to her Dad and she just needs to respect him and us all a bit more and be polite to her family.
She kicked back at me saying we weee picking on her and has now stopped talking to me and her Dad - she hardly ever talks to her sister. it’s her 21st this week she’s told us she wants nothing to do with us and we can cancel the meal and I said so you don’t want any presents or the surprises I’ve planned she said no she would just go out with the BF
She is still avoiding us in the home and not speaking this is not the first time we have fallen out over her behaviour but this is a storm over nothing and it’s breaking my heart
My family have said tell her to leave she either behaves respectfully towards her family or she can move on she’s an adult now but that feels so final
Any advice
