If you can’t afford junk food then don’t buy it. He isn’t helpless, he can go and get it himself... maybe he will realise the cost, when he’s putting his own hand in his pocket.
I’m not gonna criticise you for feeling the pangs of the financial sacrifice, I’m sure it’s a huge lifestyle change. I get that.
I also think that you’re both adults and you’re responsible for your own kids (harsh I know... sorry)!
Some people are saying you took your boys abroad and his girls went to butlins; how is that entirely your problem? That’s his choice as much as yours. I don’t necessarily think it’s fair by any means, but I don’t see how you can be blamed for it!
I do think though, if you want to do something about it then it’s entirely down to you to step up. You’ve made the choice to partner with a man who’s got children, and those children don’t have any say in how they get treated. It’s not their fault - if you’re committed to him, you’re committed to them, you’ve got to try and be fair!
What’s to stop you applying for those management positions now, in other chains? There are hundreds of vacancies in the hospitality sector where I live and recruitment is tough at the moment. Don’t defer your financial issues and sit moaning about your affairs; sort it out :)
Instead of posting on here with all these people jibing at you, you could be polishing up your CV and getting out there!
