This is my first post since I joined but I felt so much empathy with seasider's post that I was inspired! The behaviour she describes is exactly that of my husband. I'll never forget him saying when we first met (after weeks of telling me how he didn't like baked beans), when I put beans on his breakfast one day, I put most on my plate so as not to waste them. He looked at the two plates and said, 'I see you've got the lion's share of the beans!' A bell rang in my head but I decided to give him the benefit of the doubt.
Since then, it's carried on in the same vein - I once bought two family size pork pies from a renowned shop. We ate one for tea (shared between 6) and put the other one in the fridge. When we got up next morning my daughter asked where the pie was. It had vanished and eventually he admitted that he'd got up in the middle of the night and scoffed down the lot. It made him very sick though. When he pours wine, he always overpours into his glass and has been known to pour both glasses back into the bottle if I mention what he's done, and storm off into the kitchen, open and drink a whole different bottle. He grew up with two brothers - the middle one is okay but the third one is even worse than my husband. Btw, he was born after the war but tells people stories suggesting he was part of it. He even takes my experiences and retells them as if they happened to him which can be totally irritating. I often wonder if I should have left him but he's a good man in lots of other ways. I always put his odd behaviour down to insecurity and anxiety and, being quite a lot younger than him, make lots of jokes about his poor memory etc: I also give him a big portion of meat, fish etc; to keep him quiet. This generally works but there have been some dreadful arguments over the years as he says I'm mad and imagining things if I question what he's done. I'm beginning to wonder about the autistic spectrum now after reading your posts but thanks for sharing and making me realise it's not just me.
