Hi WFM...Thanks for visiting my thread. I've read also your story (although not finish yet) and I can see some similarities in our sitch.

one thing to add, I co-own a business with my h too. Makes it very difficult!


Yes! It is indeed extremely difficult seeing/working and at the same time detached. Me and H get along well, when we are at work its purely business/work...but also friendly at all times and yet distant...but in my heart there's always this hope and longing/wishing that it would somehow be more than that.
