Travel show you are trustworthy, and are also capable of supporting yourself.
However, it appears your soon to be hubby works for BT (is a senior electronic engr in a major telecom company in UK). If at any point in the relationship he breaks down, stops working etc, you will have to wait 60 minutes before you get through to him, probably being cut-off in mid sentence......then any repairs will have to be booked weeks in adance at a cost
