Couples match is definitely not a fun thing, but I can tell you, having watched my roommate struggle with trying to follow her fiancee to a location is probably worse. They were lucky that he was able to do his prelim year at our medical center, but figuring out how to rank her programs to be close to him and exploring the options of moving his residency has been nothing but trouble and extremely stress-inducing.
Doing a year of research makes the most sense, I think.
Also, plenty of women plan weddings during normal years of medical school, even third year, so don't let that stand in your way.
