I don't see my boyfriend's family a lot, mainly as he isn't very close with them due to issues with his parents divorcing at an early age. However, every so often we go out with his grandma and aunty on his Dad's side. His aunty is quite strong willed, blunt and has made comments to me before that were quite rude. However, I am always pleasant and chatty with her as I know it means a lot to my partner. Today, we were supposed to be meeting them at half 2. I woke up with one of the worst migraines I've ever had, couldn't shake it by that time and was practically bed bound by it almost to the point of tears. I said I wouldn't be able to go and to apologise for me. My boyfriend returned later telling me his aunty had commented "she could have at least made the effort", and "well she obviously doesn't like us then". I messaged her to apologise and she hasn't accepted my request nor read the message. I find this upsetting as I would never act this way if any of them were ill. I feel like this has happened as the time before this when we were supposed to go out I was dealing with a recent family death and wasn't in the state to go. I just feel like I'll get the cold shoulder next time we go out. Am I being unreasonable by being annoyed at this response?
