I know you already know this, but it is IMPERATIVE that you don't forget again to transfer the necessary funds to meet your family's needs. Your wife has probably made note of your slip-up, and in the frame of mind she's in right now, she WILL use it against you at some point, you can count on it.
Make a note in your Outlook calendar or set an alarm on your cellphone if you have to. Keep the majority of your funds separate, but do NOT forget to transfer the funds necessary to meet your family's basic needs.
Document everything, and I do think you should see a good family law attorney -- preferably one that specializes in "men's rights" and men's custody issues -- and at least get a consultation.
