You sound like my ex boyfriend, similar situation. We were together for a time and had to broke up because I moved to another country. None of us took it well but we still kept in contact cuz we were more mad at the situation rather than each other. I still have some kinds of feelings for him and when he told me he got together with one of my close friends back then a few weeks ago I told him I didn't wanna talk to him, he said he wanted to stay friends but truth is it wouldn't work out. Like you said yourself... you should move on to other people, and that's what she is trying to do so I'd say no, it's not possible right now at least for you to stay friends.
