I am completely crap with money. My partner is obsessed with it and it really impacts our relationship. He has savings - about £70k. I have none. I also support my 2DSs from my first marriage (16&13). I know I need to budget and start to save but it's a whole mindset change that I need to stick with. I don't know how and our mortgage is about to go up £1000 a month. It's really getting me down and stressed.
What can I do to change learnt behaviour x
