NYE we have arranged a party at our house. Mostly DP's friends but also a group of mine too. DP had his friends around last night also and they had drinks and xbox whilst I took the kids to family party. I got back around 10pm, put the kids to bed, DPs night had turned into a full on party more or less but I simply asked him to keep it down and went upstairs to study. Came down at around 11.30 to get a drink and on the fridge where DD had made a 2012 calender with a snowman on the front one of those idiots had drawn a huge ejaculating penis coming off the snowman's head. They were in hysterics when I went into the kitchen so must have known I would see it. I didn't mention it at the time, just went back up to bed but have since told DP that because of what he did I am cancelling the NYE party and going out with my friends instead. He says I am "Totally over-reacting" and need to "get a grip".
AIBU ?
