Getting in late with my two cents...
There is nothing wrong with taking a break from CDing -- it's healthy, and helps you get your bearings. In my own case, I wish I had pulled over to the side of the road and taken a reflective break more often, and perhaps I wouldn't have driven down the wrong highway for as long as I did, and I might still be an active CDer.
If you do stop, or take a break, make sure it's not from guilt, because there is no reason to feel that way. But if things are just getting a bit too intense, or confusing, feel free to step away from the skirts for a time.
As far as stopping completely, while I agree that there is some validity to the "once a CDer, always a CDer" theory, there are some people who do it for a time, then walk away from it. I haven't dressed in over a decade, largely because of burnout (or "girlout") from having unwisely attempted to transition when I had no business doing so, but also due to economic, residential, health and personal factors that make the notion rather problematic. Do I still consider myself a crossdresser? Yes, I do. Will I ever dress again? Maybe, given the right combination of situational factors. I have a mixture of both fond and remorseful memories of my "Pink Period," but I do not have the urge currently to don any feminine finery.
In your case, walk away for a time if you feel the need to do so, but be open to the urge reasserting itself.
