So I finally told her as we talked before going to bed. I guess it worked out to my advantage that I told her on the same day I bought it (Saturday).
Of course she wasn't the happiest woman in the world, but she was glad I didn't keep the secret from her for longer than a day. I was hoping she'd be more angry than disappointmented; but no, she was more disappointed. Funny how woman can do that to you.
7 years down, at least 7 more to go right.
I did sleep on the couch Saturday night, lol.
The world is balanced again.
