I think it's perfectly normal to want to grasp onto anything you can to keep a connection. I certainly did the same when I first came here. I still do have some connections, but for me I know see that I need to sever those as well. Connections will only make it harder for you to detach and move forward.
Detaching is so hard to do, and I'm still working on it. It does get easier every day though. Getting out, enjoying life and focusing on you with the added component of time will get you to a good place.
Have you read DB/DR yet? Or perhaps 5LL, or any of the books often mentioned here? I've found that each has helped understand relationship dynamics, and is also a good way to spend time when you don't have GAL things going on.
