My husband and I have been doing this since late last year aswell, although I'd say we are more poly than ENM. He now has a partner whom he sees 3-4 nights a week, and I have a bf interstate. It works well for us, so much so that we've been openly honest with those close to us who live in our small town. But it's not all good things when others find out who aren't in our circle. Sometimes I wish we'd kept it private longer
