DP was meant to spend Christmas Day with me and my family and I’m going his for Boxing Day with his lot - mainly friends .He’s a very untidy person ( or plain bloody lazy ) and has been going on for weeks that he has to tidy up before Christmas. I’ve offered to help him. He’s just rung me to say he has to stay at home tomorrow to sort his place out and won’t be coming to mine .He’s had 365 days to do it ! Still expects /wants me to go to his Boxing Day . My family will have bought him gifts . I could do tit for tat and not do Boxing Day . But that seems petty and I’d genuinely like to see his friends. He gets on with my family - so I don’t think it’s an excuse . He’s just failed to get his arse in gear .
