Like me, my husband married his ex-wife when he wasn't fully cooked. He'd had a LOT more experience than I ever had in the area of romance. He married a woman who is incredibly intelligent, talented and beautiful. A lot, you'd think, for me, his second wife (and third significant relationship) to live up to.
But despite the fact that she is an incredible, well-travelled, and all around smart woman, I am not concerned when my husband sends her e-mails asking for advice or offering it, or spends a couple of hours a month talking to her on the phone. I am unconcerned that they go out of their way to have coffee or lunch together if they happen to be in the city at the same time. Even though he tells me how incredibly smart she is all the time. Even though I've never actually met her.
