Tired of it all being my responsibility

[Shitfuckoh]

I love my children, very very much. I obviously can't imagine life without them but I'm getting more and more annoyed at the fact that their father & his family can pick and choose when they want to be involved in their lifes and expect me to fall in to line.

Their father moved out in March. He sees them for an hour or 2 a week on average. His parents expressed that they didn't want their relationship with the children to change at all so I have made sure I keep them updated with news, pictures etc but their interest has dramatically died off. They aren't replying to emails, they don't call, they don't seem to have any interest in the children at all.

Things have been rough, had to go on to Universal Credit & budgetting is difficult. I've had to replace quite a few household things for the children which have left me extremely short, at no point has anyone even asked if I'm struggling. It's always about what works for them, what is in their benefit, how they're struggling with x,y,z.

Just.. fed up. I know it's their loss, I know I am so lucky to see my children every day, to put them to bed & to hug them whenever they/I want/need. I know all this.

Stop sending them pictures and emails! Let him keep them updated. Maybe they just wanted the pictures and updates to show their family that their "good" grandparents (but they're not).

Is ex paying maintenance?

*they're good

You are right, they'd usually call the children on their Birthdays to say Happy Birthday etc but no such call as happened yet. He said they may be waiting for me to call to thank them for the gift - why? They'd usually call, they claimed not to want their relationship to change, if things haven't changed in their eyes then do what they'd have done previously!
No he's not. It took quite a while for him to even move out due to finances. I've tried to raise the subject of maintenace quite a few times but he's always claiming to have no money.

I've had countless amount of school shoes & trousers to buy since he left, as well as new bedroom stuff for 1 of the children, on the basis of I wait until next year - it could not wait!
I know I need to get on to CMS, I've delayed it so far hoping he'd see he needs to provide for them, it's not going to happen is it. He's having a social life, going out with his friends spending money, whilst I'm trying to work out how to manage on what I have for the next 3 weeks and trying to sort out 1 of the childrens bedrooms on what is basically nothing.
