I really don't want to break up 
Been 'together' a couple of years now but long distance.
A assured B at the beginning of the relationship that they had absolutely no problem relocating-nothing much keeping them where they were. If the relationship worked out they'd be the one to move, definitely. However they've now changed their mind on this for various very valid reasons. Not totally changed their mind, but reluctant and confused.
B was reluctant to start the relationship at all. Didn't want long distance. They'd had a turbulent time where they didn't really have a proper home for a long time (long story!) and had just got one when the relationship started. They'd also been living a long way away from family for years (over a decade) and had just managed to get to be able to move back near them and definitely did not want to entertain the idea of moving away again.
I'll describe each party's situation further.
A lives with parents. No assets or savings. Left school very young with no qualifications although did go to college and get one later on in life. Despite this, they have a job that in terms of these circumstances is very good. Decent pay and perks, four day week, they're comfortable there.
A is also autistic which presents in ways meaning finding work in a new location would be very stressful for them and quite difficult. No money to fall back on. Finds new situations and changes very stressful. A is however a bit fed up of their job and in some ways would like a change. A is very close to some family members and spends a lot of time with them and would really miss them. The area A lives in is a seaside town, high crime rates and low house prices. A wants B to move to their area and rent a place with them for a year or so then maybe think about moving to B's area.
B has a house with a mortgage in a decent yet inexpensive area. Also has four buy to let properties. Not much in savings, roughly £3-£4k but some nonetheless. Only close to one family member really. Quite high qualifications in different areas and would likely be able to find work in a new location easily-a lot of jobs in their fields would be WFH too. A bit of £ to fall back on if couldn't find work straight away. B is not working much at the moment anyway due to recent redundancy so will be looking for new work in a few months when a contract ends. B feels that A would have a better life here with them, they're understanding about A's autism and take care of their affairs a lot. B does not want to rent due to being a landlord themselves and it seeming silly (not to mention expensive) but doesn't want to buy in an area they see as undesirable (and wouldn't be able to for a while anyway due to work situation).
Neither of us want to split up-we love one another. We're not young either.
But this conversation began happening a few weeks ago and we don't know what to do-neither of us want the other to be unhappy.
Any opinions at all welcome.
