I don't think it's about a fear of commitment in general, but making the wrong commitments.
I think the song is about how so many people get married for all the wrong reasons, namely the pressure from family and friends to get married, have kids, settle down, buy a house, etc. and how this person realizes where this road leads down and knows that it will not give them happiness, but rather a sense of disappointment. Thus, you need to look at what are the reasons behind making a commitment, and the singer is remarking how unfortunate it is that many people make such decisions for all the wrong reasons.
I agree, this is good but overhyped.

But that's just me.
