When you entrust him/her with your personal finance situations,he/she will like to keep track of your spending....That means war.If you love your peace,keep this things to yourself and also keep off from his/hers.

Hapo guka amesema!! Although each one of you will manage their own Finances, Communication is key so that you update each other on the projects/investment/funds available. it will also allow both of you to discuss and formulate a way forward on items like budget etc..

My partner is a spendthrift and i a saver how do i entrust her with all my financial information?

Gikomba kulikuwa na matope sana leo.... lakini nimefika.

Well, my thinking is not very far from @Njung'e's... but i would say, it all depends on who you have in your life.... I would expect that he/she does not use your card (whether he/she knows your PIN or not) without informing you unless that is the agreement.... In some occasions, its just inevitable to reveal to your partner your PIN because you could be stuck out in the bundus and you need some things moving while you are away.... now, what she/he does with the card at that time or later after the knowledge of your account status determines if you can trust them or not. This is not an issue that can be generalised... But if you know your spouse is the type that will breath down your neck to explain the last coin and how you spent it, then may be you need to think how to relate.......

Thank you guys for your insight.....

Seems i was right to trust her.... but I have learnt. Next time i need yo put a limit on how much she should spend.....
