I personally do not find anything wrong with a spouse or significant other being your best friend. You're choosing to be in a long term relationship with this person, they should, to some degree, -be- your friend. My husband often laments that we didn't meet each other sooner because he wanted a friend that he could trust and love and fall in love with.

Greatly OT, I picked up your book today, and I'm hooked already. <3 Somebody hid it behind a magazine rack at the bookstore, however, and that greatly annoyed me.
