He was probably lovely for a year because he was you boyfriend and making an effort to impress you so you would like him. Being friends straight after a break up is never going to work cos you still have all those feelings whizzing around. It takes time to get over someone and you need to give yourself that time. He is trying to make it work with someone new and you're bugging him. Why should you ask him to keep it off Facebook? I understand it hurts, but that is why you cut yourself off, you ignore him for as long as it takes. When you can finally think of him without welling up and you can look back smile and you can know he has a girlfriend and be happy for him, then you are ready to be his friend. I'm not saying you're entirely in the wrong he shouldn't have gone mental ad yelled at you, but I do think it was unfair for you to ask him to talk to his girlfriend about sparing your feelings and I think it was utterly stupid to try and be his friend when you still love him.
