Basically just that. We have been together for four years and while I love being with him and we are in love and get on great, he absolutely won't make joint decisions.
This is basically on everything.
Where we live, finances, what car we have. Everything. So when we decided a couple of years ago that we wanted a "joint" life, we discussed what we wanted but then he just does completely different things.
So for example, we might agree we will like in Berkshire and I'll arrange my work around Berkshire and then out of the blue he'll say "I have just gotten a job in Kent!".
He has done this with everything. He doesn't tell me he wants the thing, he doesn't discuss it, he doesn't consider me. He literally just does it and then tries to persuade me afterwards that what he's done is a good idea.
This worked the first few times, and now he's done it again and I feel very depressed and disappointed.
I think he has a kind of psychological block on the concept of a "joint" life choices process, but he wants to live a joint life (where I just keep adjusting my own life around him).
What to do?
