Duffy is engaged. He accepted Mel's proposal. But the trips to Ikea, dinner parties for couples & talk of babies are giving him itchy feet & now hes not sure if he can say goodbye to his extended adolescence & face up to that final walk down the aisle. How does he know if shes The One? Can he cope with responsibility? Does he have what it takes to become Mr Commitment? Because if he doesn?t, he may just find that hes lost Mel forever.
