Back story; my mum (dad not really on scene) of 3 daughters in 30’s- I live with DH and DC (9). My 2 sisters live with DM - both sometimes stay at boyfriends. One sister (L) I get on with and we have contact. Other sister (O) and I had a disagreement 5 years ago and she took the hump and hasn’t spoke since. This got my back up as promises she made to my DC were not carried out - likely to get back at me.
I sent 3 texts over about 3 months attempting contact (from a let’s move on perspective) but no reply.
Unfortunately DM loved the drama.
DM uses this to her advantage and for example will ask to spend her birthday day with my family doing something she wants then will go out in the evening with sisters.
I have known this years and just got on with it but this year it’s like she has been quite sly/ demanding and it’s annoyed me. She’s booked a meal at a fancy restaurant for her and my sister’s- my family and I aren’t invited, she knows DH stays with his own DM Mother’s Day weekends as she is far away so it would just be me and dc. She in fact text to say her late afternoon and evening are taken so where are we (me and my dc) taking her in the day but she needs to be back for 4pm to get ready to go out for her meal.
My DC has no idea about the depths of above. I asked her what she wants to do on Mothers Day and grandma can come but she said she wants a day just for me and her. I actually like this idea as we rarely have this and while it fits with how annoyed I am with DM I also feel guilty.
AIBU to not take my mum out like normal? DC would ‘let’ grandma come but I then feel like I’m not listening to her wants of a day for the 2 of us.
I can’t split the day as I can’t take DM home easily without our day ending there so she can have her other plans.
I am deep down annoyed with DM as she could ‘help’ my dc get her auntie back (even excluding me) but it’s like she prefers it this way as she gets double everything- years ago it would be 1 outing/ celebration for us all.
Everyone irl is biased so asking on here.
please be honest I can take it.
Thanx
