Sarah Fox: What would you do if your spouse were going to another state to visit an old friend that he sees a couple of times a year. The guy is a bigamist with 2 wives and is bringing in a third which your guy thinks is hot. He drops clues at every turn but tells you nothing is going on (never mentions the third woman) and refuses as he has most of the time in the past to have you accompany him on the trip. When I say I don't get it, he says, you don't have to get it. He knows I am very open to new adventures and willing to try new things...tho we have not. How can I stop the woman from going there from across the country or make him take me.
