What makes a guy commit / want to be exclusive?

I find it interesting that sometimes a woman can be exactly what a guy says he wants on paper (I. e. attractive, intelligent, kind, whatever else he is personally looking for etc. etc.), but yet a guy is not always inspired to commit to her. So I'm thinking there's got to be something more that inspires it? I know one of the dating experts for women (Renee Wade) states that it is a formula of attraction (enough that he wants to keep coming back / won't lose its appeal) and VULNERABILITY (that one surprised me), that makes a man want to commit. Her theory is that if a woman is just attractive but doesn't open up emotionally (and sexually) to a man, if she doesn't make herself vulnerable in any way, a man will not feel like he is needed in any way and will not be inspired to commit. This does kind of make sense to me, but I'd like to hear it from you guys (and girls too if your guy told you what inspired him to commit to you). Is it really as simple as attraction and vulnerability, or is it something else? I can't help but think it's not just whether she meets a list of traits, as I have literally in the past had several guys tell me that I was "exactly" what they were looking for attraction / personality wise, but they didn't want to be exclusive. For some reason I felt comfortable right away with my current guy showing him my emotional and vulnerable side, and lo and behold, he did want to commit to me... So I'm thinking there COULD be some truth to what this dating coach advises. So guys, is this it, or am I missing something?

Also this dating coach considers herself a "femininity" expert, so she is coming from that slant...(I am quite feminine in nature so I personally love her blog and her outlook on male / female relationships, which I just recently discovered, and that's what's got me thinking on this now)
