Pinhead, That's what I am thinking too, how do I start setting boundaries? I agreed on freedom because of the DB techniques saying don't ask about R, don't ask about OW, don't talk about the M . . .
Angel,
"Don't talk about OW" isn't the same as "be willing to have OW present in your marriage." Clearly communicating to your husband "I will not live in an open marriage" is NOT the same as constantly badgering him with questions about where he's been, who he's been with, what is it that OW's got that I haven't got, etc.
You are mistaking "let them go/give them space" with "give him freedom to conduct his affair."
