perhaps you could write to him then he has no choice but to listen to your side of the story. and its easier to put your feeling out on the page then to say them straight of your head cos u get confused and anxious and things come out all wrong. tell him everything, even what you are going through now. i understand how hard it is to move on. im broke up with the love of my life 5 years ago and have found it impossible to move on. (there's a long story behind it all- read my post if you want) so tell him everything and if that doesn't help the situation then he's clearly not worth this suffering you're going through darlin.
