For feeling upset that my aunt involved my estranged parents after I asked for help?

Your aunt can't be trusted so I'd seriously consider going NC with her too.

Unfortunately it’s not really the place of the person asking for a favour/money to put demands and restrictions on the person they are asking.

We don't know anything about your aunt or mums finances. If they are wealthy then perhaps they could have helped you without speaking to your dad. If money is tight you are being unreasonable to think they can find the money without involving him. You want to be independent of your dad and never communicate with him but in that case best not to ask your mum for financial help as they are a couple and will discuss things.

Have you got a job lined up? If so and it's a very short term cash flow issue can you get a money transfer from your credit card (if you have one) to your bank? This is an offer like a balance transfer but cash and not the same as withdrawing cash on your credit card which is very expensive.

If not (again if you have a credit card) can you use it for the things you can like food and petrol to keep any money for rent and bills.

Have you put in a claim for universal credit? If you were previously working you should be able to claim new style Job Seekers Allowance.

Your aunt is a bit of a flying monkey...
Involving her was a mistake.

Agreeing she could talk to your mum... another mistake.

Aunt was in the wrong but she wont see that... in her mind shes helping.
Also fammmmmlllllllllllyyyy

It may also be your mum involved your dad which isnt your aunts fault.

Sorry this has happened.

Boundaries are not controlling other peoples behaviour but only about your own. If you didn’t want your father to be consulted you shouldn’t have agreed for the aunt to speak to your mother as this was an obvious risk.

Yanbu if thats what happened but are you sure your mum is telling the truth? I think it equally likely that your aunt spoke with your mum as agreed and your mum went and spoke to your dad and is telling you that your aunt did it to avoid accountability. I would speak to your aunt about it and tell her what your mum said to figure out if it's the truth. If it's true though I'd be reconsidering the relationship with aunt too.

Most couples would discuss stuff like this, it was unreasonable to think your mum wouldn’t speak to your dad before parting with hundreds of pounds to someone who’s chosen not to have a relationship with them. It was a mistake to ask your aunt I think. I hope you find another solution.

How much money do you need? Would your dad not have noticed it leaving the account?

You’re not being unreasonable at all. Your aunt crossed a line and had no respect for your decisions.

How did he message you if he's blocked?

Also, he can't be daft enough to think you can 'just come home', when you have a contract with your landlord?
