Is there a difference between and DA and commitment phobe?

I was just wondering because my long term relationship w my ex is a major commit phobe but my most recent relationship was w a total DA. They reminded me a lot of each other but the DA had more distinct characteristics of a DA. My commit phobe seemed like a milder version of a DA. The commitment phobe wasnt dismissive w my feelings and didnt run the same way but definitely wouldn't commit to anything in his life. I mean not even having a car payment or buying a house, all that was too much of a commitment.
