well I can answer in my case...
My husband is in his home country where we met and married. I traveled back and forth for a couple of years. We then became pregnant, I came here to birth and I applied for citizenship. My n400 application took 2 years to process and then was denied because I stayed out of the country more than 6 months. Because I was always waiting for my oath ceremony I never went to visit, wishing to go as a citizen...
Finally, the application was denied and I filed again. I am leaving now after my prints are done, just in case I end up in the same situation. I am still not in the clear with the time out of the country, they could deny me again, but I hope not...
Frustrated alot has been through a really long frustrating wait, I feel for her.
