If I watch something in bed and he comes up, I have to turn it off immediately otherwise he'll go into a sulk the next day or that night.
This thread is bringing up so many memories - especially this part! My ex was exactly the same. If I was reading a book in bed and he came upstairs, I had to turn my lamp off or read elsewhere. If he was reading and kept me awake, that was fine. If I hurt him accidentally, I would need to keep apologising, if he hurt me, it was either a) it didn't hurt or b) a crappy apology and told to get over it.
Some days he'd talk to me normally and an hour later he would sulk and give me the silent treatment. I would have no idea why. Or he'd come home from work and give me the silent treatment, wouldn't say why or anything.
He sulked when I went out on my hen do, he sulked when planning our wedding and I would just have to deal with everything on my own (stupidly I still married him). He sulked (and laid everything at my feet) when we went through IVF...
A few years ago, the day after my birthday we were out and about, he started sulking, I would try and make conversation, he would ignore me and play on his phone. He badgered me into getting his other phone from our room and said nothing else. We went out to dinner, he would not talk or look at me and was obtuse when talking about what we would order.
Eventually he tells me we should split up, that we want different things etc, at first I felt awful - like it was my fault, but I realised it was him. So I stood up for myself for the first time, agreed that we should split up. He had the audacity to ask why I wasn't fighting for us?! Idiot.
I grew up in a house where my dad sulked and my mum pandered to him, she would apologise, cook his favourite food etc. so it was normal for me.
Like you OP, I walked on egg shells for years, I changed my behaviour so as not to piss him off and he did hit me (and was intimidating) a few times over the years, which meant that I modified my behaviour even more. I also looked forward to when he would go away with work as I had peace and wasn't worried.
He's gone now and there is relief, coming home and knowing there is no one at home but me is amazing. Luckily we couldn't have children so I never have to see him again.
