We are having a birthday party for DS. It is mainly just for toddlers but we have invited grandparents etc. My cousin has a 1 year old so we have invited them but we weren't planning on inviting all aunts, cousins etc. However I did invite another cousin who I am close to and who takes a real interest in my DS, (the above cousins brother) and I didn't want to invite their sister. We fell out years ago and are polite when we see each other at other families houses but thats about it. I don't like her, she is very two faced and a compulsive liar and not the slightest bit interested in my DS (or any other children) anyway. She has also fallen out in a big way with the cousin I am close to as she is being a total dick (but thats another ridiculous story).
My nan thinks I should invite her, to keep the peace etc but I don't know tbh. I don't like her, she is nice to my face but I know with her everything is about a front.
WWYD?
