We have been to couples counselling to talk about polyamory and other relational issues, but stopped last January, before I cheated. We haven't been back. The counselor was not against polyamory, which was good, and helped my husband work through some of his feelings and thoughts about it. So my husband now accepts that I am bi-sexual and polyamorous, although he cannot accept behaviours or me living a lifestyle that is bi-sexual and polyamorous. We may have to re-visit counselling at some point, but I think we will need to see someone new, and our town is very small. We are moving in a few months, which will open up counselling options.
Thanks for your reply
