Can I be honest? I am not sure about cutting contact with my father.
Please do be honest. I totally get that it's a big deal, cutting contact with your own father. Massive.
I still want him too like me and be proud of me
That's normal. Unfortunately, he's never gong to give that to you. You're flogging a dead horse. There is no way in this lifetime he will give you what you desperately crave from him. I'm so sorry.
The only contact I have with him is about the 2 middle children. How do I tell them they can't see him?
You'll find the right words. Something like "grandad isn't being very nice to mummy, so he's not allowed to see us any more. Let's go and do [fun thing] today instead!" Xxx
He gives them pocket money (I can't afford to) he takes them places (I can't afford to) I know that sounds pathetic written down.
He does that to control you.
Kids don't remember, or value, money the same way adults do. A day out with wellies splashing in puddles, or to feed the ducks (peas not bread), or to a free or cheap attraction, playing tag in the park, making a den at home, or a movie night on the sofa with a bag of popcorn, a blanket and whatever film is on tv that day, is worth just the same to them as expensive cinema visits etc. Pocket money? 50p or whatever you can afford or just go without, they're too little to really care. Or tell them pocket money is replaced by treats night, and once a fortnight you all have ice cream or whatever.
I have 1 dd (3 ds) and my biggest nightmare is that she ends up like me when it comes to men
You know the risk of that is much higher if you allow them contact with him.
But they like seeing him. How do I tell him?
Covered above
He is expecting to see them on Sunday. The shitstorm it will cause...
Allow him this time and just don't arrange any more. Yes It will cause a shitstorm. Block what you can and buckle in for the rest. The storm will pass.xxx
