AIBU for not giving my half siblings the same financial help?

I have 2 siblings and 2 half siblings who are my dads.

I’m in a good financial situation, so 5 years ago, I gave one of my full siblings some money to help her buy a house and also for fertility treatment. I told my other full sibling that I would help her with money if and when she needed it. A few months ago she found a house she wanted to buy so I gave her the money.

My dad knows I’ve done this as my siblings told him, and since giving the latest gift, he and my half siblings are asking if I’m going to gift my half siblings the same, as they both rent and one is also wanting fertility treatment.

I get on ok with my half siblings but I don’t have the same relationship as I do with my other siblings. One of them has now stopped speaking to me and the other is piling on the pressure for me to gift them the same. They’re also trying to make me feel extra guilty for not at least paying for fertility treatment one of them who is struggling to conceive.

My dad has said it’ll ‘change the family’ if I don’t treat my half siblings the same. He ignored my text asking him what he meant by that. He has now ignored my birthday.

AIBU for not giving my half siblings the same as my full siblings?

What would you do? I feel like I should be able to spend my money however I want to. I’m mostly annoyed at my dad as my relationship with him shouldn’t depend on what I give to his other children.

I think you should have kept quiet and insisted your siblings keep quiet too about your donations.

Advertising it has created problems.

Why did you want people to know?

She didn’t advertise it. Her sibling told their father, not OP.

Sounds like your dad has a lot of money. He should be paying for the half sibling’s IVF.

Your dad and half siblings sound like a load of cash grabbers. I would say you’ve had a major financial setback and you have made agreements with the 2 siblings you gave money to, to pay it back to you on a monthly basis. Obviously don’t make them pay it back, just lie.

if you don’t smooth this over somehow, he might cut you out of his will. So I’d lie to smooth it over. I didn’t tell lies back in the day, but nearly 5 decades of life has taught me that lying is a useful tool/skill. The best lies are close to the truth. Have you any house issues that you can say cost a shit load? Major leak/roof shit

You can do what you want with your money. No one can demand anything from you.

Although I suspect you think less of the siblings you refer to as “half siblings”. I always think that’s an awful term.

I’m not surprised your dad thinks it will “change the family”. As all his kids are equal to him in his eyes.

You’ll just have to accept ‘it is what it is’ and that your “full” siblings are blabber mouths.

Genevieva · 29/05/2026 00:07

Took just have to apologise and say you can’t afford to give any more help to anyone. House deposits and fertility treatment are serious amounts of money. They can’t just be rustled up without consequence.

Wecanbeheroes26 · 28/05/2026 23:52

The way your dad & half siblings are behaving says it all! You are right not to want to give them a penny (nor are you obliged to). They see you as the cash cow.

I’ve read all your posts. I wouldn’t give them anything.
Their dad can step up and put his hands in his pockets.
Well done for helping your siblings.

CypressGrove · 28/05/2026 23:28

You don't need to give money to anyone, but you have been quite naive not to expect this outcome. Money and family is always super fraught. It's a shame everyone didn't stay quiet.

CatherinedeBourgh · 28/05/2026 23:22

'It should really have been their father who helped them out but you were always a deadbeat dad to the three of us so I had to step up to the job.'

I've read all your posts, OP. Under the circs - two very separate families - I am not surprised that you want to help your full siblings more than your half ones. I'm surprised that your half-siblings would expect the same, given that there are two very obviously separate factions.

Whether you want to even things up depends on how much money you have and how much of a relationship you want with your half-siblings for the rest of your life.

Why should the half siblings expect OP to fund their deposits? How entitled is that!! Do they care about the relationship or Op’s money?

FraudAbroad · 28/05/2026 23:10

can none of them fund their own homes or treatments? It would never occur to me to ask my sibling for financial help? I have a very wealthy sibling in law and we never ask for anything. I think the half siblings are greedy, if they want family help they should ask their mum and dad first. You do with your money what your want and maybe your siblings need to be more discreet too.

Hellohelga · 28/05/2026 22:58

Hell no don’t give money to half siblings. It wasn’t your choice DP got divorced or that DD had a new family. You may not even keep in touch with them after your DD dies. They all sound very grasping. Your siblings are with you for life.

Would you want a relationship that you have to pay money for in order to have?!

@ 99, great message.

That could be a thread in itself. When our parents split up, he didn’t see the 3 of us for almost 2 years whilst he got himself sorted. He reappeared with a new wife who was pregnant and started seeing us again. We were 16, 13 and 9 by this point.

He ran his own business and my mum has always said he must have hid money as he didn’t have to pay much in maintenance, pleaded poverty, yet he always had a very good lifestyle and was very successful. His other 2 kids got everything whilst he hardly paid anything for us and my mum worked 2 jobs as we got older to support us.

My dad has apologised to my mum and us for his behaviour back then and obviously none of that is my half siblings fault, but the situation made me and my siblings very close to each other and our mum. I don’t think my dad really realises the damage he did and he has made sarcastic comments about our ‘perfect mum’ when we defend her if he says anything negative about her. She’s not perfect but she did a bloody amazing job when he deserted her with 3 kids and we won’t have him even joking about her.

He was a decent father before all that and I know he feels a lot of guilt, which he should. That’s another reason why I’m shocked at his behaviour over this.

Families!

Thanks for all of your responses. I’m going to walk the dogs to try to clear my head.

WELL.
Knowing that my message would be : You can support your younger children dad, you’re pretty financially comfortable, spend the money you hid from cms so you didn’t have to pay maintenance for your older children, after all Jane and Bob are the children you gave everything to while we struggled and mum worked two jobs to keep us afloat. Ignoring my birthday is pathetic and I thought you’d gotten past the periods where you were a crap dad and didn’t see us and didn’t support us. My siblings and mum are my world because of those years.

Your money is yours to do with as you see fit and nobody should be pressurising you to give money.

However I can see how it might be hurtful to your half siblings that you favour your full siblings and them wanting the same as your full siblings may not so much be about the money but about the treatment and not wanting to feel "less than".

To them and their dad tho, it's all about the money. They're measuring their relationship on what they can get from the OP. The OP has already said she helps them out in other sisterly ways as well as nice gifts.

Anyone with an ounce of sense would realise that half siblings are different. I bet they wouldn't give the OP money and I bet all of the fathers estate will go to the 2nd family's children, esp if the dad dies first.

Happyjoe · 28/05/2026 22:23

The fact they are being shitty towards you tells me you did the right thing. Your money, your choice.

OliviaBonas · 28/05/2026 22:07

Your dad is the one who has behaved badly (for decades!) not you. If you have spare money, treat your lovely mum.

wherearethesnacks · 28/05/2026 22:04

he must have hid money as he didn’t have to pay much in maintenance, pleaded poverty, yet he always had a very good lifestyle and was very successful. His other 2 kids got everything whilst he hardly paid anything for us and my mum worked 2 jobs as we got older to support us.

Why would you care what this creature thinks you should do with your money? He's completely immoral.

EveryoneIsAsleep · 28/05/2026 13:49

I didn’t expect this to happen.

I can not even imagine hearing that my half sibling did something for their full sibling and expecting the same from them, because my relationship with them is nothing like as close as the relationship they have with each other. Obviously I underestimated their (and my fathers) sense of entitlement.

Yeah, I started reading your post thinking you could have handled things better - then got to the part where the younger two are hounding you for money and your dad's emotionally blackmailing you!

For that alone, they deserve to get a big fat nothing. Appalling behaviour, making it clear they don't care how much they hurt you as long as they get their hands on your cash.

I'm sorry, this must be upsetting for you.

MeridianB · 28/05/2026 21:54

Your dad and your half siblings should be embarrassed by their deeply unpleasant, grabby behaviour. Ignore the tantrums. You’ve done nothing wrong.

The only thing worth changing in future is keeping anything to do with money completely private.

Bamboozle30001 · 28/05/2026 21:46

Don't give them or your dad a penny!!!

I can be a bitch when I feel like it. If he raised it again I'd be very tempted to say you were giving your siblings the maintenance he didn't provide when he left your mother. His new children were well looked after and now you are doing that for the children he left behind.

FrizzyFrizbee · 28/05/2026 21:34

@EveryoneIsAsleep it’s really awful what your dad has done, and I wonder if he has a hidden motive in all this, namely a ‘legitimate’ excuse to disinherit you from his estate, by saying he has every right to redress the balance by leaving his estate to them and not you,

Why? so that he doesn’t have to think about making a provision for you should he die before his new wife. Maybe he is worried about the grief he will get from her, especially if they are talking about wills just lately. His new wife may be objecting and demanding everything is left to her. He is maybe too weak, is looking for the easy way out, or his new wife runs rings around him, could that be it?

On the other hand, if his daughters need help it’s on him and not you, but he has already shown the kind of person he is. I’m guessing his new wife gets everything in his will and it then passes to her daughters, and he dubiously justifies it to himself because you chose to help your sisters.

Not a nice way to treat your daughters, whatever the reason, so sorry OP.
