I am in the same boat but it's reversed. I am the Canadian, and my husband is the American. We are going to wait for our approval before we move, but we originally discussed that if it took a long time, we would do a similar thing. I would move back with all our stuff, and my husband would fly in with just his bags, making it easier (rather than being together in a car) to say he is just visiting. I don't want to alarm you, but we submitted my husbands paperwork on November 4, 2014, and we only just now received Sponsorship approval (3 months later), and still need to go through the Permanent Residence approval. It's taking a lot longer than those who submitted a few months earlier, and the timeline is getting even longer with every update. Just be prepared that you most likely will not have PR status, and you will need to ensure you choose the best way to cross the border. You don't want to piss of the agent and get blacklisted. Make sure you demonstrate every aspect that you are just visiting, like posters have said before. If they look you up, they will see you have a Permanent Residence application on file, and will grill you on visiting, so make sure you have some sort of paperwork trail bills/bank statement/house that links you to the US still. Good luck!
