Lived in Dundrum, had a nanny (4 boys under 5 as it was then), hubbie had big corporate job, spent endless mornings wandering aimlessly around Dundrum Town Centre. Bought a holiday house in Wexford, tiny village, 2 pubs, postoffice/shop, church and pharmacy. Beaches 5 mins, heart of countryside - fell in love.
Ditched Dublin, hubbie took redundancy, took a year off and settled into country life. Hubbie has sent up his own accountancy firm, 4 boys play outside everyday, we've made fantastic friends and I now realise how lonely and miserable I actually was in Dublin. We have 1/10th the money we had in Dublin (hopefully this will gradually change) but are a million times happier.
Wouldn't go back in a fit. Only thing I miss is family support with kids etc but looking back we didn't actually have that much in Dublin, everyone was always too busy.
