What does mmmmm dificil d ir mean in Spanish?

This means something like "um, hard to go." Depending on context, this may be referring to someone wanting to go to an event but having difficulty doing so, or perhaps someone needing to leave but not wanting to. The correct way to write it would be "Mmmmm, difícil de ir." (The "mmmmm" is just a sound, not an actual Word, so the "right way" to write it is debatable.)
