If it has unraveled "upstream" of your FD you should replace it sooner or do all your rides in the smaller ring until it's replaced.
In my experience the RD wears out faster than the FD as I use it much more. 2000 miles sounds too soon, maybe the end cap fell off and got the process started???
If you want more detailed info, you will have to post a decent pic of your situation.
You can replace it yourself if you have a set of cable cutters, a cable should not cost more than 5 bucks and it is VERY easy to do.
PS I suspect most folks would suggest replacing cables annually if you ride a lot, i.e. more than say 5000 miles/year. You might be able to get by doing this every 2-3 years but a broken cable mid-ride can ruin your day.
I hate to do this but.....+1.
I have had cables last for years on bikes, other bikes they need replaced in six months. In your case it sounds like the cable end crimp was loose or missing. If that is the case and it happens again (on a different cable of course) put a new crimp on it, tape it up, or solder it. Without some type of cable termination (can't think of a better name) the cable is going to unravel sooner than later.
