Partner is going to a sporting event next week with friends. it's been booked for ages. no issue with this. He then drops into conversation that his adult son is going with him too. He said it in a cagey way for some reason and then said his sons fiance was also going. I wasn't invited this time, although he did used to invite me but our relationship isn't great at the minute, so he probably wants some time away. I didn't say anything but went a bit quiet. He said but you don't want to do this activity anyway. I asked if the fiance was doing it and he said no. So she's been invited, even though she's not participating but I've not been invited. Am I being petty or would you be upset too? He has done a few thoughtless things and I feel like I'm very low on the priority list right now in many ways.
