Why are they like that .......?

I broke my friendship recently with my Virgo friend, and i have send him two emails and one message. My first email was a angry email where i told him that he took me for granted used me and that i f*** trusted him and so on inclusive the f word in it... No answer....Then my second email where i told him that is better to go our separate ways we tried many times to be friends but no result and that he is right that it wouldn't be the same anymore like it use to be, and that i don't want to end this bitterly No answer, But the thing is i'm still bitter about how he treated me so i send him a text (Whats App) message with: I still hate you, he reads it but no answer. Why are Virgo men like that?
