Partner spent my money and lied

So is this your husband you’ve previously posted about or another newer partner?

Call the police and stop letting him screw you around.

Tell him it all needs to be back before the end of the week or he's out. Your mental health will vastly improve without him dragging you down when you aren't in a relationship with him. . Then seek police advice about the money.
You have given birth and are raising dc I'm guessing without much help from him? You can kick ass and get your life in order more than fine without him.
Contact cms and get some money that way also.

If this is the case and you were given the money as trustee for your kids under terms of the will then you’ve breached your duty as trustee and you are liable for this.

If you’ve inherited and decided to give part of your inheritance to your kids then there’s no issue so far as trustee duty of care, but it’s sickening that he’s done this.

Its also true that unless you have a written agreement there no evidence for small claims court. Morally he should repay it but he doesn’t seem willing. If I were you I’d be wondering what else he was screwing me over on behind my back.

And indeed similar to what the OP has done. She is the executor and trustee for the children and has given their money away.

Looks like you owe your kids that 5k.

You knew he was a pathological liar (your own words) yet you gave him your children’s’ money as a test? It’s on you, all your fault. I would work out how you are going to pay them back. Do you work? Are there any other issues going on with you? The reason I ask is this is something a sibling of mine would do and there is a reason why.

The absolute best case scenario is that this loser finally gives you the remaining £5k.
I can definitely guarantee that he will keep the interest as "he's earned it for his trouble"

Use your head now. He said end if the month so play nice until end of the month- get money ,then run. If it goes sour he can prolong this and it'll get costly so see if he comes through on that promise first.

Reminds me of this case. The mother and grandfather have been prosecuted and must pay the money back many years after stealing it in similar scenario to what the children's father has done here https://www.bbc.co.uk/news/articles/c780r74m9m2o

It's at this point you leave this person. They fundamentally cannot be trusted and they will rinse you dry. This is a major red flag, I would leave my partner under such circumstances. Trust is a critical component of a decent relationship.

Also glossing over the fact that she is in breach of her duties as their trustee and has caused the loss to the children including the interest they should have earned.

You need to be aware that you are the one legally at fault as Trustee under the Will though. You chose to put their money somewhere that was in breach of the trust for the children. You are the one who could actually be held liable for their losses.

And I have said why it makes no sense. Why would you not be able to open an interest bearing account?

If the children were listed in the will as the beneficiaries of the £15k, you can’t just “draw a line under it.” This is fraud. 1/3 of their inheritance has been stolen. The father of these beneficiaries is not allowed to keep £2k and give £3k of it to a mate’s dodgy “investment opportunity”.

Why give him the chance to fuck her over again?

OP, if you’re not physically afraid of him, could you nab his phone and try to transfer the money to yourself? I’m sure you can guess his passcodes.

Yes, and someone will be along in a minute to say that’s a crime and oh no, but at this point, match his energy.

OP, I am sorry sorry that he has done this to you and to your children.

His comments are classic coercive control. It sounds as though he has isolated you from friends and family and now he is undermining you, gaslighting you and telling you that only he cares about you and will support you.

This is not true.

You are worth love and respect in your own right and there will be someone to care about you and take care of you in your future.

For now, I would recommend contacting Women's Aid to get some concrete support. He has committed financial abuse, and by not giving you the £2,000 that he does have, he is controlling you.

To other posters, on the face of it, the OP may appear to have been foolish, but men like this are clever about what they do. He may have encouraged her to use his account. The higher interest only makes sense if he kept it in the account. So while the OP could have invested the money better, we have no idea if she was coerced by him to take the action she did.

Women who are controlled often feel things are their fault, when they have been manipulated into the situation. So please show some kindness and support.

Because she shad years of his abuse and might be paralysed by it?! So let’s maybe not perpetuate condescending to her or telling her how shit she is? Because that’s what he’s been doing and it’s obvi fucking worked.

Some of you need to take a long hard look at yourselves. I thought I had no empathy, but Jesus Christ.

I am really really sorry this has happened. I would assume the £5K is gone and just draw a line under it and walk away. He has shown you many times who he is so hopefully this is the final straw.

As you said - he's a cheater and an abuser and is useless with money and doesn't even pay his way. You had to have known this was a massive risk. I'm sorry you are learning your lesson and even sorrier your children are the ones who will pay for it - quite literally.

£2.5K isn't a massive disaster in a lifetime so I'd just take a breath and start planning on how you will disentangle yourself from this man. And whenever you falter, remember that he is 100% ready to ruin your life and your children's lives if you stay.

So what is the advice and support, given that she's going to stay with him and keep doing these things and she and her kids will suffer? Everyone she knows IRL is telling her the same thing as the 'sanctimonious strangers' on here. It's not really kicking herself to say 'I knew he's a liar, cheat, and useless with money, but I gave him it anyway and he knows I won't do anything and will stay anyway'. She just wants to be upset and have people say there there, you're too kind, poor you. If that's what you're advocating, I can't see how that's helpful.

You would potentially have a greater support network without this man. Your siblings appear to have withdrawn because they are fed up of hearing about what he has done and then watching you forgive him. If you left, they might be more supportive of you. Also, you think if you got ill that THIS man would look after you?!

Well you’ve clearly not posted for advice, on the basis you’re ignoring literally every piece of advice here.

Get him to transfer the £2k NOW and give him a deadline for the remaining £3k. If that doesn’t materialise, kick him out.

Cool, super helpful comment.

Your posts were some that I reported.

It’s not unreasonable to think their own father wouldn’t do this. The clue is in how horrified people are at what he’s done: it’s unfathomable.

Now back to berating the OP.

Well it certainly shows some parents don't prioritise their kids.

Yes a £300 difference if it was for a full year but who needs a year to open a savings account. Say it takes a month then loss of interest would be £25. A real incentive to hand £15k to someone who's let you down repeatedly.
