I'm just interested to hear what you do. I earn 20x what dp does but I am not a spender at all. I was brought up by hippy parents who didn't believe in possessions so I don't find spending money makes me happy. So generally every month I only spend money on travel and food. I am a generous and kind person when it comes to spending money on others though as I understand to other people that possessions do mean something!
Dp is a spender. We have our own separate accounts but also a joint account (which only I contribute into because dp's salary is used up on child maintenance and spousal maintenance and then things like his phone bill). Dp is a greater user than me of the joint account as he works from home and does all the shopping and the cooking.
It hasn't actually bothered me till recently when a) I think his spending has upped a notch, it's almost as if he wants something he just gets it and he buys stuff every day b) his ex has been implying she should get more maintenance as she knows I'm a high earner and feels dp is living the life of Riley.
I can afford the money in the joint account but what would you do? I find it hard to rationalise this because buying stuff is so meaningless to me...
