My cousin is having a 1st birthday party for his DS this week. My cousin has invited us after deleting me from his facebook and saying he won't go to mutual relatives house if I am there due to an incident with my DS and his DS and stuff (unrelated to our DS's) he was writing on facebook. I don't know why he invited us but I wasn't going to go. However years ago his mum (my aunt) fell out with me over a ridiculous thing over me not inviting her daughters BF to my wedding and she didn't speak to me for many years. It has only been since I had my DS that she is finally talking to me again.
I have also had a bit of a run in with my younger sister and her mum (we have the same dad) has got stupidly involved and is being very very petty. I have just found out that they are going to be there too.
My DH has pointed out that if we don't go (and subsequently we now have to invite cousins DS to our DS's party) my aunt could get funny again, so I feel obliged, but I am really really dreading it. It is going to be very awkward and I really can't work out why we have even been invited. AIBU?
