If your wife would be willing to take over the administrator account, there's a plethora of features that Mac offers in their parental controls you'd be able to benefit from. Aside for using it to set restrictions on your web access, you can also determine which programs can be run and during which hours. Most of all, you can restrict access to your account - or to the internet - during all odd hours of the night. This is one way to make sure you only use the internet when there is company. A very responsible thing for an internet addict to do.
