Long term relationship, rent together, kids, everything split 50/50. He earns more.
My DP seems to keep track of any money i've borrowed from him and i don't know if that's petty or if i'm taking the piss not paying it back immediately. I'm not talking big amounts of cash, it's purely when im taking the kids out somewhere that i think you may not be able to pay card or a couple quid for parking ill ask if he has any cash to save time on going to cash machine as im terrible for keeping any on me (not an issue with my spending etc i just don't visit the cash machine often thats all) this is not something that happens all the time either but he will remind me i haven't paid back a tenner or use it in an argument sometimes e.g. if im complaining about something he hasn't done round the house (he hardly lifts a finger) then he'll say well you haven't paid me back. I have no issue whatsoever with paying him back i just have a brain like a sieve.
It works both ways, the other day he took all the change i had i think about £4 to buy a drink but i don't expect it back and will never ask him for it. If i have money on me i'm happy to give him some if he asks.
How does everybody else's relationships work, am i being unreasonable to ask for money from him?
