Longish story - my bf has just finished chemo last month and I had suggested a celebratory dinner tonight with her and her dh and my dp and me and she said yes.
So checked with my mum @ 3 weeks ago and she said that she would check her diary (-don't ask!) and if I didn't hear from her to assume that it was fine. Didn't hear from her so assumed all was fine and arranged just didn't confirm exact time.
Anyway haven't heard from my bf - she has been away so text my mum this morning to say we hadn't heard from my bf but dp and me would go out anyway if she was still ok to sit (assuming she was). Dp has been off for last 2 weeks and I have held off asking her to sit at any other time as was looking forward to tonight and had assumed she was sitting.
I sort of politely said in text don't worry if you have made other plans - just being polite though as hadn't anticipated she would have.
She replied that she was sorry but had made other plans with her mum and dad and elderly aunt who is over visiting them to go out for dinner.
I was really upset and annoyed - we do have a rocky history and have recently been to counselling together.
I feel that she doesn't mind letting me down but won't change her other plans after she realised she had double booked - I am expected to understand. I don't go out very much at all and had been really looking foward to tonight so AIBU or not?
