Well it won't take Georgie long to meet someone else ... Dec's loss hey? Dec's got serious issues with commitment so it seems.
It's good they've split if she wants children- She needs to find someone to be a father as time is passing. Maybe that's it? Maybe he actually isn't interested in having children so it's fair enough if he wants no commitment of the sort. Not everyone is obliged to do the family thing. Perhaps he'll find a like-minded partner to share his years with. The loss would have been for his girlfriend if he'd stayed with her for much longer when she may be seeking another type of relationship.
