To talk or not to talk....

Should i try and fix things between us? We had such a laugh together and i want that back. But i'm not naive enough to even consider that if we did get back together things would go back to be exactly the same as they were before - too much has happened - I don't know what to do!!!!!! I mean yes, i did what i did and that done something to him, i understand that but all i asked from him was to be there and listen. But instead he ran away and dealt with it by ignoring me like i did him a personal wrong. I didn't, But maybe in his mind i did... Oh i don't know, if only i could read minds. ARGH! I don't know what to do!!!!!!
