Ok DS1 is turning 13 soon, I have arranged a surprise party for him at a venue he is familiar with.
Mainly just family and the few friends he does have.
Everyone in the family know about this except DS1.
So yesterday I am out with my mum and DS1 when she says to him "As you are going to be 13 this year would you like me to pay for you and a couple of friends to go for a meal in the evening of your birthday"
Now I couldn't say anything because he was there obviously but when I got home I messaged her and asked why she said it and her reply was well it will be nice for his 13th to be celebrated. I mentioned again that I had arranged the party and she replied well I don't think he will like that.
AIBU to think I know my son better than her FFS. She knows the work I have put into this and to keeping it low key so he doesn't find out.
I have ordered his cake etc and I really feel she has just ruined it all.
