Jane,
Thank you for sharing such a personal story. Indeed those situations are rough. What I admire in your retelling the story is how you owned your part in the breakdown. Somebody must be the first person to do so. What it tells me is that you care deeply enough about the partnership that you are willing to openly admit to your contribution. Heck, you even wrote a blog post about it, offering it up as a lesson for us all. That's noble.

Shawn
