I'm not an expert, but I've been exploring vulnerabilty as a means of healing. It may have something to do with generosity: our vulnerability often gives value to those who experience it, and it may have something to do with empathy: we receive it only when we're honest enough to allow other people the opportunity to express it.
Either way, I think your willingness to open up to your partner, and your readers, can only serve to bolster the healing process.
Well done.
