I think it is okay not to love someone after only a few months of dating, even if the lust was strong in the beginning.

Instead of 'taking a break' you might try old-fashioned dating, which is where you lead your life, the other person leads his or hers, and you get together for actual dates, which involve activities like going out to dinner (or cooking dinner at home), seeing a movie, meeting friends for coffee.

By extending the dating period, you get to see someone in a variety of settings, and you get to see how they respond to you and to others in those settings. Also, you get to see better how the person is over the course of a year or so.

The way I see it, your 'commit phobia' might just be healthy skepticism over the initial warm fuzzies we feel for someone we are initially physically attracted to.
