How to not let the ex win

[Defrump]

She is weaponising the children which is sad and I ignored it at first but surely this behaviour is not normal?
Tells them that my partner broke her heart
That he is a liar
That he lies to everyone
That he doesn't love them.
My partner admits he should never have got with her but doesn't regret his kids but she is poisoning them against him even tho she moved on first and has new family.
What would you do?
I'm not leaving him just looking for ways to deal with her poison. Thanks

Why wouldn't you put jam on hot Cross buns?! Big blob of butter then jam smeared on top. Heaven! (misses point of thread)

I totally hear you. But unfortunately DD4 has weak enamel on her teeth and the dentist has told me to limit sugar.

@Theunamedcat Plum jam on a hot cross bun is very, very nice.

I'm so trying this 💓

Re treating them bad, no quite the opposite. He had them all through lockdown and she wasn't bothered at all. Only when her new partner's parents commented that she seemed like a bad mother did she start wanting to see them.
Obviously I would take my partner's side but he really is a good dad, not Disney etc, got good boundaries with them. He is conscious of not doing anything to manipulate or cause them unnecessary stress so backs off when they want to go to their mum but it breaks his heart.

If he had them all through lockdown it really doesn't sound too bad, OP - sounds like he is building good relationships!

It's natural for them to sometimes miss the other parent when they aren't with them, and like I said, they are probably saying the opposite to mum when they are with her!
