Fucking bastard ex.
We were together 12 years. Have 3 kids.
Circumstances mean he sees them at mine. He lives with his mum who is not safe for the kids to be around.
He pays me £50 a month maintenance which goes directly to a joint loan we had and the rest of the debts we split evenly.
He has been buying junk for the kids, and for me, not that I accept it. He then moans I haven't accepted his offerings, so I give it to the kids.
Yesterday he complained that he had hardly any money left and asked me for £10 to cover the junk he had bought that week. I told him I couldn't afford that but would give him £5. So I transferred him the fiver.
Today he started sending messages. Originally asking about a party DS1 has been invited to, then got onto money, asking where all mine had gone (er, I have rent to pay, 3 kids to raise and I'm not getting a free ride off mummy)
And kicking off about all the stuff he had bought. So I sent him another fiver and said we're even. Drop it.
He carried on, kicking off, basically wanting more money. I asked if that's what he expected and he said the £10 was just for this week 
Pretty sure that he's meant to pay me for the kids, not the other way around considering I'm the resident parent and he only sees them 10 hours a week!
Anyway, I told him I would only speak to him from then on regarding the children.
He carried on sending messages, basically telling me if I'm that skint to not buy takeaways (I bought a takeaway last weekend for me and the DC as a rare treat and they mentioned it to their dad) and shit.
As if he still has a say in my finances.
AIBU to think he's still trying to control me and to ignore him unless it's about the kids.
(I know I'm not. I just need to vent.)
