Commitment Phobes

I wonder if this quote from Rob in "High Fidelity" is telling of how men's fear of commitment actually hinders them.

"I can see now I never really committed . . . I always had one foot out the door, and that prevented me from doing a lot of things, like thinking about my future and... I guess it made more sense to commit to nothing, keep my options open. And that's suicide by tiny, tiny increments.
