Money is a super touchy subject for me and my wife: it brings out the worst in me. I suppose its the un-dealt-with resentment of years of badly spent cash!
I've felt for a long time that my wife and I shouldn't have a joint account. A joint account is between two trusting parties, and obviously that was not possible.
She's finally into recovery and I think it might be the wrong time to send the message that closing the account sends, although she says she is willing to do it if I insist. To her it symbolises a further separation on top of that which we have already made.
One of the draw back is that if we have separate accounts, and try to share the expenses in some other way, we will have to have more rather than less talks and communication around the subject of money.
