yeah, there isnt even a question here. Commited monogamous relationships are about 1) honestly 2) equal views on the terms and conditions of the relationship. Your friend seems to have neither and nothing but bad things can come from that. It almost sounds to me that he likes this girl (thus doesnt want to break-up) but is afriad that commiting to her is a declaration of becoming old. If he continues with this pattern, he will surely detroy the relationship, and in 5 years when he realizes that "bachelor freedome" is crap, and a loving monogamous relationship is soo much more free, and amazing he'll feel like quite a dick when he realizes what he gave up so he could get head from a gold digging blonde 20 year old.
