Yes- you were. I would think twice about asking you to any get togethers in the future.
I always tell my daughter that once she makes plans with a friend she can't change it just because something better comes along-its rude.
My DD7 tries to pull this all the time. Makes plans with a friend then when something better comes along she wants to change it. I do not allow her too. I think it is very mean. However, although still inconsiderate, I think the OP's situation was different. It's not like a great sale at her favorite store was introduced. She had the chance to spend some family time with her DH included. Inconsiderate, yes, unfortunately. However, I would not hesitate to invite her to something else.





Of course... this is the CB, and one can't help but mention that if you'd only been raising a household of liars like some of us there'd be no hard feelings...
