I want my partner to put her pay in our joint account
What makes you want to put her pay in your joint account?
Cuz I haven't decided whether to marry her yet
When partners merge their money into a joint bank account, it can create frustration, resentment, and maybe even some financial problems. Talk to her about this and make sure this is the right move for the next step in your relationship.
She texts me all the time and asks me to transfer her money.
It sounds like there may be a communication problem between you two. Have you considered opening a joint bank account for both of you rather than either of you transferring your pay checks to the other persons bank?
