Slowly -
any possibility you can start going along on those business trips? Or at least have phone sex with him while he's there?

I know I never appreciated how lonely my H got on those trips (he's very extroverted and doesn't need much time alone - unlike me, I'm the opposite.) I would always have very practical reasons not to go (who would watch the kids, he'd be working most of the time anyway, why spend the money on my ticket, etc.). Since the bomb I have made every effort possible to travel with him when he goes, and he really appreciates the company SO much. And you know what? I get to stay in nice hotels, work out in their gyms, have lunches with DBers all over the country (okay, San Francisco, Boston and New York so far, but you never know when I might be coming to your town, guys!!!) and the nights with H are pretty great

So - instead of focusing on OW fears - why not figure out a way to travel with him.
