Thankyou so much everyone!!
I've registered on greataupair.com so far. I'm going to work for a few months and save some money before I start actively looking for a family to au pair for. I'm really nervous about - you hear lots of scary stories of of people who've had bad experiences! But hopefully should be fine.
I went and saw his mother this afternoon which was really nerve racking for me as she can be quite emotional and defensive of her children, but I knew I had to go and see her. It wasn't so bad, but his brother and sister are quite cranky at me ... Something that I hope will stop once they realise its better in the long run.
See him tomorrow at the bank to sort out the rest of our finances but I know it will be fine.
Just sooooooo sad!
