Personally I don't see any problem with the email you sent. I think it was opened up by the discussion you had the other night.
You spoke your mind, said what you believed was possible, stated what your hope is, discussed some things you see as negative turning points to your marriage.
I would only say it wasn't good to send if you hadn't had the conversation you had the other night. That opened up the door for the email.
Others may chime in differently, but that's my take on it - for whatever that's worth...lol
