To not invite her?

[thatpinkpineapple]

It's my birthday on Friday.

My teen DC asked tonight if I'd like to go out out for dinner on the day. I was really chuffed as he's never suggested that before. We rarely spend time like that together, and if we do, it's always my suggestion and me paying

But now my mum has texted asking me if I want to go out.

AIBU to want to just have the time with my DC? It was his invitation to me, so feels rude to invite anyone else along, but I don't want to hurt her feelings either and make her feel unwelcome.

WWYD?

“Sorry mum me and Ds are out on Friday. I am free on Sunday if you would like to get some lunch” or something along those lines.

Stick to your arrangements and ask when your DM is next free.

Thank you. Those suggestions make perfect sense. I am probably overthinking!

Say yes I would love to but can we do Saturday night?
and stick to Friday with ds!
makes the celebrations longer too bonus!

Perfect

I would just say that you are busy on Friday evening, without mentioning DS. If your mum knows that you are going out with DS, she may feel comfortable in inviting herself along.
Suggest another evening date when you're free or, possibly, go for lunch/brunch with her on your birthday before an evening date with DS!

no need to make it in to a bigger thing than it is or do something you don’t want to do out of guilt.

YANBU. Will she invite herself along if you say you have plans with DS? Might need to be ready with a response, but sounds like she would understand?

I replied along the lines of Sirzy's response, and we are going to make plans for the weekend, with DS invited too, if he's not working. Everybody happy

IMO go out with just your son. Your mother doesn't own you on your birthday.
