I, too remember the late Sunday (and Christmas) dinners because our Dad would always put his drinking buddies first. I thought that was normal until I got to older primary school age, and saw that some fathers actually loved their children and wanted to do nice things with them, instead of all family activities revolving around alcohol......
However, my two worst Christmases were with my ExH. When our children were aged about 6 and 8, I went down with a really bad kidney infection, 2 days before Christmas. I went to the GP for antibiotics, he took one look and referred me to A&E - they wanted me to stay in on a drip for antibiotics. ExH told me under no circumstances was I to stay in hospital, how could he look after those children on his own? I felt so ill it was anything for a quiet life, but I signed my own discharge on the promise that if my temperature got any higher, or I developed worse symptoms, I would go back. By Christmas Day I was considerably worse, vomiting, very high temperature etc., but I had to carry on as he was sulking - he wanted sex the night before (which had put me in that situation in the first place - but that's another story). So I had to do everything, while he watched, picking fault with everything. That night he insisted I sleep on the sofa as I'd kept him awake the night before - like an idiot, I did. By Boxing Day I was delirious, my parents came round and he insisted I was putting it all on - they called the doctor out and he gave me an antibiotic injection and wanted to send me back to hospital - ExH lied and said he would look after me at home, with my parents. He sent them home that night and I just had to get on with it. I did eventually recover, but it took weeks before I felt anything like my normal self.
The following Christmas I suspected he'd been up to something for a while, but couldn't put my finger on it. He was still his usual spiteful demanding self, but had changed job and was being sent away to work at other offices. That Christmas Eve he phoned me at home and asked me to find something on his desk - he was very insistent and told me that he needed a reference number from an hotel receipt to claim his expenses. It was left plain in the middle of his desk - obviously so I could find it easily. It was from one of his 'work trips' - a room for 2 nights made out to 'Mr and Mrs'. I thought the world would cave in, I knew he was up to something but not that! Christmas day was hell - he was really playing up. like the cat that got the cream - all smarmy. I had to carve the turkey with that moron grinning at me from ear to ear - I so wanted to stab him with the carving knife! I started divorce proceedings the following year which he didn't take well, but his slapper came with lots of money and time shares - money is everything to him and his family. So that was it - Christmases are very different for me now, he poisoned my children against me so I've not seen them (or him, thankfully) in years.
