I feel your pain, having been in a somewhat similar situation myself, and my heart goes out to you.

You are clearly a highly sensitive person with a lot of empathy, and you want to heal his pain. The truth is that you can’t, and if you continue to stay in this relationship you will become more and more depressed yourself. He’s not capable of giving you what you need right now…he may never be capable, no matter how much of yourself you sacrifice. You are already feeling helpless and frustrated, trust me, those feelings will only get worse as time goes on. I say this to you from my own personal experience. I hope and pray that one day he will heal, but when and if, that day comes it is not in your hands. I hope you find the strength to consider your needs in all of this.
