Honey, I had ONE friend when I was living in Egypt, we would manage to meet up once, maybe twice a month. 'H' didn't really allow more than that, but we were text mates and would be chatting all day. She kept me going, she kept me sane. This was the friend that X tried to ruin the friendship with. He always used to moan about his ExW and her friend, and how friends ruined the marriage. Hmm, I wonder now why her friend told her to meet him in a neutral place the last time he wanted to talk to her. He met her in a refuge for DV victims, she was with him for 8yrs. He said he never beat her, but I'm guessing she was so traumatised, she never put her self in the firing line. Betting he did control her though... I'll never know now....
Gah, your description of the row aftermath is so stereotypical. Isn't it a total BORE to have to put up with this? That's what I used to think, it's so needless, pointless and as you say, a fore-taste of the rows to come.
One day you will have the strength to say, Actually, I deserve an apology. Actually, your cup of tea is nice, but it's a drop in the ocean.
Are you afraid of him?
Meditate on this: what IS he actually going to do to you? if violence is not in the picture and he is going to verbally attack you and perhaps intimidate you, then surely you can say, Actually NO, that's not on. Admitted, I was only able to say any of that when I'd had 8m here in the UK on my own.
The pain condition is clearly not helping, of course that's going to weaken you and your resolve. You are going to have to dig deep, deeper than you have ever dug before to get the strength to stand up for yourself, but you are worth it. Your children are worth it, and your life is worth it.
You are a work in progress, if you are serious about getting him out of your life, you have to commit to that and enlist all the RL help you can.
