being entitled doesn't mean you get whatever you want...just because you want it. i'm entitled to my privacy. i'm entitled to be trusted by the woman i'm with. as such, should she not trust that she have no need to access my accounts...to invade my privacy? why do i have to be hiding something because she have no business in my personal business. if you walked into your living room and found your man digging through your purse, wouldn't you be offended that he was going through your stuff? yet, he's entitled to do so.
DO YOU GIVE YOUR ACCESS INFORMATION TO YOUR MOTHER/FATHER/SISTER/BROTHER? if not, does that mean you're hiding something...or that whatever's in your accounts is none of their business...and you don't want them in there?
in the case of a mate, it could just mean that they want you to respect what's theirs...and understand that what's theirs isn't necessarily yours...even in marriage. that's why you have individual accounts and joint accounts. if you want joint information, get a joint account--email, phones, etc. i didn't give up my life just because i got married. i still need ME time...i still need MY space...i'm still an individual. WE are one. i'm just me...not us.
i would be uncomfortable with her asking to access my accounts.
if you and i were together...and i asked for your access information, wouldn't you feel disrespected that i didn't trust you...that i would think you were trying to hide something from me...even if you gave it to me? would that inspire unity within the relationship?
