You found out that your partner of 8 years had been seeing a psychiatrist and not shared this with you?
Background. At the time of us meeting it was clear that he suffered with what I would call a complex web of emotional difficulties. He had always treated people poorly, I believe a projection of his own poor self esteem (not excusing the poor behaviour) and been unsure in his identity. I am aware of some things that happened to him during his childhood that haven't been dealt with. He didn't have a very 'stable' upbringing. Our relationship has endured a lot over the years, but I thought that we were stronger for it and in a healthy place. Previously it seemed that he felt comfortable speaking with me about anything.
