Why do I get the feeling this is more "long distance" for the past 8 years?
Text message/ emails.
If something happened a few months back that he did not discuss, hid as others have said, there is no trust, this is not the right guy for you in any event.
However, I'm concerned about the bombardment of text messages, putting him down, constantly telling him he has hurt you, over and over and over and over, off course he's had enough now of all those messages. What has he got to go by, what has he got to remember, be happy about?
You made the bed, now you must lie in it. Blaming someone over and over and hurting them and putting them down and telling them it's their fault, that you don't love them, etc, etc, etc. Is not the way to encourage growth and love within a relationship.
If he did not commit to you over 8 years, he never will. If you felt that by doing the blame game and put downs was going to make him marry you and realise what he had, it was never going to happen.
Be kind to yourself, go learn how to love yourself, find someone that you get along with and laugh and love and are happy with, after. Don't sit back 8 years wasting your life on someone that is not suitable and if you were in a long distance relationship, try one next to home next time.
