Just so we're using the same vocabulary, what do you mean when you say "open marriage" ? Do you have romantic relationships with other people, or is your openness restricted to sex? This question isn't intended as a judgement, just clarification so we can understand you better.
Gralson: my husband (works out of town).
Auto: my girlfriend (lives with her husband Zoffee).
The most dangerous phrase in the English language is "we've always done it this way."
