For not paying half when I'm leaving.

I don't think that you taxiing him around can be considered part of the equation here. You did that because you were in a relationship with him & chose to do that rather than him getting public transport or a taxi. I don't think that you can retrospectively say 'but I drove you here and now I want that to be taken into consideration'.

You made a financial commitment. You need to pay.

You’ve been paying your share for living there. He wants you to pay half for fixtures and fittings he is going to keep. Your agreement to pay half was based on the assumption that you would be living there and using them. Personally I would just tell him that your half of the stuff doesn’t come free of charge. If he doesn’t want to pay for it, I would take half of it. Divide the white goods at equal value he gets the cooker and washing machine, you get the fridge freezer and dishwasher- however it works out best. You take half the blinds and rip up half the flooring and take that.

Or he could just accept he is now the sole owner and pay for them.

You agreed you would pay him back half, that means you also wanted to spend that money at the time but didn't have your share. You really should still pay it imo

Just fob him off and tell him you'll pay him back something when you've got the money and get the hell out. The words he's using against you are horrific

0nce you are out you then don't have to pay him anything ! He's not got a leg to stand on

Obviously you must not give him this money. It was agreed to verbally because you were both going to be living there and enjoying these items. Now, only he will benefit so obviously you cannot and should not pay him. Just don't engage with him, get out of there asap, do NOT give him your new address, block him and move on with your life.

You agreed to pay half. Nothing in writing-presumably no text messages or anything saying you agreed to pay half?

However, you did agree, so morally you need to stick to your agreement. In reality, without documentary evidence of a 'contract' to pay your half he doesn't have a legal leg to stand on.

However, you can't pay half for items that you will not get the benefit from - eg: carpets, flooring etc. I suggest that you work out what your half is & take it in the form of removable goods - fridge, cooker, curtains things like that. He can keep his half in the form of the carpets, flooring etc.

You can sell the things that you take if you don't need or want them.

Agreeing to pay half for those home improvements would only be reasonable if you were going to be gaining a stake in the value of the house. If your relationship had worked out, and you had your kids and married and decided to share your assets in common henceforth, then that's a reasonable investment. However, that's not what happened, you have not gained a share in the assets and he is retaining 100% of the benefits and the value of them so not he doesn't get to make you pay. If he wants that money back he can sell his enhanced-value house with the new flooring and new blinds and new kitchen appliances, and buy a skanky hole with bad flooring, he can then pocket that value difference and he is set back how he was before you moved in, without you being unreasonably poorer.

So how about you take the fridge freezer, then deduct the cost of that from the amount he has spent overall.
And promise to pay him half of that when you can in instalments.
He really can’t expect you to pay half to what he’s spent when you’ve only had use of them for 8 months.
And actually the way he’s speaking to you, he sounds like a nasty shit, so I’d perhaps stuff him and walk away.

I think that if I were in your situation I would be looking at a compromise.
When these items were purchased, did you have any say at all in the choice or did he just go out and buy them? Who paid for the deposit for the property in March?
Yes, things like blinds and flooring can’t be taken, but the white goods can. So, figure out the cost of those, pay him that amount and take them with you.

I've said to him if he wants to move then I'd find a way to pay for what he has in full as it would then be my house. Obviously I can't take half the floor and blinds as it stands.m

Your suggestion is absolutely fair. Whoever stays in the house pays for the goods.

Please don’t let him bully you into paying.

Remind him that you have fees and deposit to pay for new house.

Who paid the deposit for the current house? Is he giving you that?

If you pay half, you keep half. So in this instance you leave with things that are not fixed down.
ie washing machine, fridge.
He has a choice, he can keep the stuff he has bought & will be profiting from. or you pay & keep half then he has to replace at his cost

Well of course you dont owe him half now.

but i'd be really petty and pro-rata the cost of how much ive used them based on expected lifetime of the appliance. So e.g. a fridge lasts what, 6 years? Work out 8 months usage of that and pay that type thing.

But if you're living there, why wouldn't you pay half bills/rent?
How often do you taxi him about?

The only mistake you made was telling him. Of course give him nothing towards this.

Set up sone sort of payment plan, but you agreed to go halves on that stuff so you should do.
