Ex’s belongings at my parents for over 2 years

After 2 years I'd stuff them in the bin, and never speak of it again.
If he ever pops up again I' d just say " I thought you collected them. They re gone".

Do you know where he lives? Take it round there and leave it in his front garden. If you don’t know where he lives now, take it to his parents and leave it with them . After all, he left it with yours for years, so fair’s fair.

He's forgotten about it, and so should you! My council allows you to put bags of clothes on top of the recycling. Or imagine the relief you'll feel putting it in one of those big clothes bins! I would sell the best bits if he had expensive tastes.

You could text him with a 7 day deadline. It's not your problem if he's blocked you.

For goodness sake, don't listen to the posters telling you to bin it or sell it at this point. You HAVE to give him a deadline to cover yourself legally. Otherwise, unlikely though it might be, you could be setting yourself up for a world of pain.

Ten days is ample, as he's local. If you think he's blocked you on WhatsApp, send the message by SMS and/or email as well (or get your parents to send it). Then, after the deadline, charity shop the lot.

Sounds like he’s had plenty of time so don’t think it’d be unreasonable to just get rid but the other alternative is to message him saying you’ll be throwing it away on X date if not collected. My friend did this after her ex spent several months making no effort to recover his belongings despite living down the road and he miraculously found the time to come get it once he knew it would end up in the bin.

I would message him saying they will be in parents lawn on x date and if if doesn’t pick them up by x date they will be donated. You’re giving too much headspace to this.

write and give him 10 days to fetch it or you will be disposing of it, no extensions (bar him being in hospital maybe!)

YABU for holding on to it for so long and not binning it. I chucked my exes stuff away the second he left my flat without taking it with him.

Throw it away? It’s not giving off “bad energy” unless you let it.

Sounds a lot like you've made some cash on eBay to me.

Bin it - literally take it all to the dump and chuck it. Don’t waste a moment longer trying to sell it or donate it. Don’t even bother opening the bags.

And then if he ever asks for it, feign ignorance “what bags/stuff? I’ve got no idea what you are talking about…”

Bin it and block him if he contacts you.

Sign up for a storage account in his name on their free trial. If he ever pays the bill he'll get his stuff back.

Could you get a friend (a man?) to message him on SM saying if he doesn’t make arrangements to collect the stuff by x date you will be getting rid. (If he does want to collect it just arrange for the bags to be outside at a certain time. You don’t need to see him.)

Take to the nearest charity shop. Inform him they are there. He can buy them back if he wants them.

He left this stuff at your parents house. So get one of them to text either him or his parents to say it will be disposed of on x date (eg this weekend) if not collected as they are moving, and he will need to let them know 48 hours before.
If he does say he'll collect it, you can leave it outside their house immediately before he's due. If he doesn't reply, then get rid of it.

There really is no much legal recourse
for him for personal items left behind for over two years. He can try it out if he can afford a solicitor and court fees and time off work for some bags of clothes but how likely is that? Bin it and if he asks say I do not know what you are talking about. And then shut the door. He won’t come looking for them and it’s been way too much thoughtfulness on your part and inconvenience on your parents part.

I would do as @Whyherewegosays. If you have someone who could message him to say,

‘following on from Allroundtheworldd’s various messages asking you to collect your belongings from her parent’s house. She has asked me to contact you to say the items you left there will be available for collection on [date] between [small time window] after which they will be disposed of as there is no longer room to store them’.

Dump it. He clearly doesn't want it.

Sell it if you can be arsed or just take to dump/arrange collection.
It's a shame you should have to go to any effort or cost but it is what is.

It just means get rid of, doesn't necessarily mean put it in your kitchen bin! Just like "bin them off" doesn't mean putting someone in the bin.

Bin it means dispose of it, not necessarily putting it actually in a bin!
I bin clothes regularly via the local charity shop.
It is an expression that covers dispose of!

Take it to his work place and leave it for him.

FFS at everyone saying bin it!! Do you not give a single stuff about landfill?

OP - donate it or sell it if you can. Please don't just make "binning it" your first option. You don't owe him anything in terms of trying to return it to him.

I'd get someone to message him ie not you to say "your items will be left outside the house for you to pick up this Saturday. If you do not pick them up then they will be disposed of"

Then it's super clear and I'd just take them to the tip after that
