Well you can ignore me if you like, as the number of bags I've got rid of over the past fortnight is testament to the fact that I'm no minimalist, but I think you should give your ex an ultimatum. Either he comes and gets his stuff (including his parents' things) or you get a house clearance company in and they go out that way. Give him till the end of the month and not a day longer. Or you could get the price of a storage unit and tell him you'll bill him at that rate every month, (and do it, then spend the money on a new dress, or a holiday, or gin
). Either way, he needs to pay up or get his things out of your space.
Than the charity shop possibilities. They aren't making you any money cluttering up your house, so you have nothing to lose by getting rid of them. If you can be bothered, you could try selling them on eBay or Vinted, but it's a faff, so if there isn't going to be enough reward to make it worthwhile, why not cut your losses? It doesn't matter what you paid for it once upon a time. It's how much use it is to you now that matters.
I understand sentiment over the toys, but again, if they aren't being played with, what's the point? Would a children's ward take them? Or a playgroup? That way you know they are giving pleasure to someone, and they are out from under your feet. Or you could ask at a food bank if there is anywhere taking toys for children whose parents can't afford them - that's not uncommon these days.
That leaves the technology. It's really not worth clinging to old tech if it's not working. It goes out of date so fast that you will get a lot more for your money if you have one modern working thing than paying to get three broken old ones mended.
All of that is easy for me to say, I know
. I still haven't even started on the clothes, and I'm busy all day tomorrow, so it will be Thursday at the latest before I do, and I have a lot to sort through. But if you start with your ex husband, and stick to your guns, you will probably feel a weight lift. Just having the garage space to put other things in (eg the TVs if you don't want to part with them yet) will make you feel better.
I hope you get a good night's sleep and that things look better in the morning
