Dp isn't happy about me getting a new bank account

[Justbatteringon]

About 5 months ago i got sick of dp not helping out with any bills and such he had spare cash he just frittered away so I told him it wasn't fair and to start giving me money towards the house he only works pt but agreed at around 70%. That lasted ok for a while but then he started transferring money from my account into his. So I changed my online banking password he was not happy he's still not happy.
Anyway last week my friend was telling me about her new bank and how much she liked it pretty mundane stuff , so I applied for an account and was accepted new card came today.
DP is not happy about this he's not happy I have a new card, not happy he has to pay towards the upkeep of the house, not happy he doesn't have my online banking password.
Aibu to do these things should I just give up and let him have what he wants. He's a good dad and he does his share around the house but the whole money issue drives me insane.

"It's not impossible to change his attitude to money."
Well that depends if he's otherwise a reasonable person, or if he's financially and emotionally abusive. It's very rare for abusers to accept they're in the wrong and change.

Yes, I agree it does depend on who he is. My dh, when we met, was used to his parent's model re financial arrangements, but got used to pooling everything. But then, we have the same priorities wrt spending, so it works for us. It does depend. If he is abusive in other ways, then no, you can't change that. My advice is based solely on this thread and there may well be other factors the OP has to consider.
