I thought I was sorted on the life front. I was a heart surgeon with a loving partner and two gorgeous little girls. Except my husband’s version of "loving" is lying, cheating, and sleeping his way around London. Which means I definitely deserve a refund. Unfortunately, moving on isn’t that simple. Just because I know how to operate on a heart doesn’t mean I know how to fix my broken one. Plus, I lost the receipt for him years ago, so I’m definitely getting shortchanged. But now that I’m single, am I ready to mingle?

If I’m on my own (apart from Siri, obviously) can I do this whole parenting thing?
