I've been in the same situation you're in before with regards to having a lot of mutual friends, but it's still probably not the best idea to try and get him dump you.
I will say to be fairly careful on what you do though, because if he's really emotionally needy, it may not be easy/possible to break it off without too much conflict. >>2 has good advice on that matter, but don't take it too hard if you try that and it still ends up ugly.
Good luck and drive slow. ^_^
