"I think some men hate having equal relationships and will do anything to try and exert a bit of control. Very childish, and I do feel ridiculous arguing about stuff like that but is either that or get walked all over."
This is true. It is ridiculous to have to get drawn into battles about such apparently small things, but what else can you do?
My ex would always disagree with aspects of a plan that I made, even if what he was saying wouldn't actually have a better outcome for him, just to show that he knew better. In my innocence - not trying to be arsey - I would ask him why, and he would be furious.
"I'm going to park at x, which is right next to y".
"No, better park in Morrisons"
"why? It's further and you have to pay a pound, you can get it back but we don't actually need anything so we'd be going into a supermarket with two small children for no reason"
"It's just better, park at Morrisons"
"Why is it better?"
"Why are you being so stupid about this?" [pissed off]
I was a dickhead who was quite literally trying to make the best plan, his agenda was just to make sure that he was the one making the decisions.
He also did the "calling me from another room to support whatever he was doing" thing, because obviously it would be ridiculous to think I might actually be doing something for my own reasons, independently.
He would also try to "resolve" arguments about where we were going by just going there. Then I wouldn't follow, and he wouldn't speak to me for days because I "just left him". No, you were the one that walked off and I just didn't choose to go there, and you knew I didn't want to and had good reason, because I had just told you.
He would also set off walking really fast without knowing where he was going which was infuriating when I did know and he was going the wrong way and if I couldn't run to catch up (toddler, SPD, baby in sling, any number of reasons) I would be pathetically calling after him and panting and struggling, while knowing IT WAS FOR NO REASON AS WE WOULD HAVE TO TURN BACK
Sorry, OP, massive de-rail there.
I know women who would just have looked at the carton with a raised eyebrow and the message would have got across - but they are in relationships where the husband is ready to hear the message. If you haven't got one of those, I don't know what you do.
