I feel uneasy about the idea of your revealing to OWH. Of course he has the right to know, but you should only do that if it's clear that it's in your interest.
You tell the other spouse because it's the right thing to do. And it is in your best interest. Exposing to the other spouse is not immoral, unethical, or unloving. DBing isn't about how you feel, it's about taking confident, healthy, productive, effective, loving and wise actions.
