My girlfriend and I broke up a few months ago and now she changed her phone number.  Is there a way I can find her new one?

Unfortunately, there is no way to find someone else's cell phone number, since it is typically not published publicly. The best way to find someone's new number is to ask them for it directly.  You could also try searching the web for the phone number using different methods, but results may be unreliable.
