"We came to this marriage wanting something and neither of us provided it."

And leaving it in the state it is in means you learned nothing and most likely will find yourself doing the same things down the road. Last I checked we all get married because we want that fairy tale life.

"I don't know what to say. There is so much pain."

When you say I don't know.. but then qualify it.. does that not prove that you know? This is an emotional response. To leave, give up and so on. Basically he is saying he is giving up because he is hurt. That implies that he still has no idea how to communicate with anyone.. especially you. Don't take it personal.

"I feel like I may still have a bit of life ahead of me and that feeling has not been there for so very long.
It sounds like a horrible cliche but I hope we can rebuild a friendship in the future."

I am glad he feels free. While forsaking you all together. That is an expected feeling when you give up and have someone new in your life. It is the high.. that comes with starting over. He is still not growing. He is just covering up.

I could do this with the entire email. But there is just noting of substance here. You already knew this stuff. The only way "out" of this is to learn from what you have done. Telling him that he should talk to the cute girl with the streak of blonde does nothing for him. Cause he has seen and is still seeing that same girl the way he has a million times before. [censored] that you are here.. but I cannot stress enough.. that the second you break out of doing this stuff and start getting back to "yourself" will you see a change. You are still just playing the game with him in these emails. Stop. He left. He made a choice.
