There was still a part of her that thought perhaps she shouldn't do it at all. In Andrew she had all the raw ingredients for a perfect life. Here was a grown-up, good-looking, solvent, generous, warm-hearted man who adored her. A man who adored her even when she looked like the loch ness monsters little sister and had a terrible temper to match.
