Just that really. Luckily we have moved locally and are in touch with our buyers - we've asked them to keep an eye out for him.
He only used to come home once every 2-3 days anyway and just for 10 minutes in the morning so I'm not unduly worried about him (he never forgave me for having children 6+ years ago).
However I can't just bloody well leave him at my old house!!! What on earth do I do now?!
