Ok, so the background is that DP & I have been together 2 years. We both have 2 DC each from our previous marriages and we have a DD together. My DC live with us, his come EOW and the weekends in between my 2 older DC go to their Dad's.
At the end of last year I took DP's surname and changed it by deed poll. Both of our families are well aware of this and aware that we have all the children on the same weekends.
I got a text the other day from DP's cousin asking if we had DSD & DSS the weekend of 6th October. I replied and said we did and she explained she was having a birthday party for her DD. I asked if she could give me ideas of what to get and she sent back one thing, a trolls dress up outfit for £15 (which is more than I would usually spend on a cousins DC as we don't have a lot of spare money but that's neither here nor there, if it's what she wants that's what we would buy - you'll understand the relevance of the cost of the gift further down).
The invitation arrived today, envelope addressed to DP only. (Printed invite so no names mentioned on the invitation itself). It also transpires that it's a fancy dress party so is going to be pretty expensive what with the travel there and back (over an hour away), gift & kitting out 5 children in fancy dress but don't want them to feel left out if they're the only ones not in fancy dress.
But the invitation addressed only to DP got me thinking that perhaps myself and my DC are not invited as her original text didn't mention my DC, only DP's.
AIBU to feel a bit miffed by this? Firstly I have the same surname as DP so if the invitation was to include me & my DC she could easily have addressed it to both of us. And should we call/text and ask if the invite includes all of us or not? Don't want to assume that it does or it doesn't, would rather know but don't want her to feel awkward or think we're being funny as she maybe didn't think about how it would look asking only about my DP's DC and addressing the invite to DP only if she had always intended to invite us all.
Sorry for the long post. Just wanting to know how you would feel if this happened to you?
