My bf of two years and I have very different finances and financial attitudes. I'm very much a saver, live within my means (I've done both minimum wage and well paid jobs, I never overspend), I've got a home a mortgage, not wealthy but comfortable. Always worked and saved.
Bf is also 40s divorced with kids. He spends all his (higher salary) on rent, bills, maintenance to exW and other 'things'. Both he and his exW seem to be quite 'relaxed' with money, both have loans and credit cards only paying the minimum repayable. She chooses not to work (teenage kids, so she could) and asks bf to pay extra when she overspends, he usually pays it even though he's also in debt.
Back to bf - he has no savings. He lives month to month despite earning a decent salary. Rents so no equity. If I were in his situation I'd be very stressed, sometimes he is, but then he goes out and buys patio furniture, a bbq, a new watch, whatever he fancies. Puts it on the credit card and pays 20% interest because he's already got lots on the credit card. These debts have been going on years.
For us to ever progress he would have to live in my house. It hasn't been discussed recently, but has in the past. I love him but I feel we are incredibly mismatched in our financial attitudes. He likes nice things, as does his exW. Has anyone been in a relationship like this? I would never want to end up like his 'mum' telling him not to buy things while he has debt. But realistically, he and I will always be very mismatched.
