I've been split up from my ex for 8 years. He has been in and out of our DC' lives a few times due to work but has had some what regular contact with them.
We're on a 'family based' child maintenance arrangement I.E he transfers me a random amount every month, sometimes by hundreds as I have no idea what he's earning but I know he's lying as he's admitted it to me before.
He's living with his current partner and she has a child of her own, ever since our children have been pushed on the backseat, money has decreased again and he keeps not showing for his weekends.
He's clearly not interested, the only interest he's got is his new family. My DC are starting to not want to go and see him (8&9) and want to say with me. It's causing me so much stress because I'm always the one who has to chase him about when he's seeing them. I pack everything for them when they go to his house even down to toothpaste and toothbrushes, medicine etc. I'm at my wits end with it all and I'd like some advice please.
