Hubby keeps asking me what he can do to make me happy. I think the only thing he can do is accept that I am who I am and I am in love with 2 people.
There you go. That is your need for the marriage to have full emotional intimacy between you. The need to be understood by your spouse, to be connected.
Is he willing to Open enough to hear your poly thoughts and feelings? Understand you fully, and not just part of you that are "easier" for him to deal with?
Are you willing to Close enough to be only his lover, and not see Liam to reciprocate and meet some of his needs for "exclusive?"
I don't know if any of my blog thread helps but starting on post 6
I was writing about mono-poly.
