Last Tango, I think you need not to worry about how you're going to be in future relationships right now, and just concentrate on taking care of yourself and recovering from this relationship. Sounds to me like you and your ex-girlfriend just weren't really compatible in a relationship, wanting different things, there's not necessarily any need to apportion blame. Counselling might be good, for you to talk through your feelings. So probably would going out and having some fun with your friends. We're all here too, when you need us!
