I think just seeing these puppies (regardless of whether or not you take one) will be good for you. Don't rush into if it doesn't feel right, but I think looking will help heal your heart.
(as a side note - I've never seen a Corgi-papillon cross before, but Corgis are FANTASTIC dogs. I had two pembroke welsh corgis growing up and they were both hearty, healthy dogs and lived to be 13 and 14. I would definitely recommend a purebred Corgi if you decide to look again
