He may believe that there is something better waiting for him.
Unfortunately, this is the kind of mentality that some people who do online dating have.
They have spent so much time browsing through online dating profiles that even when they seemingly find their best match, they continue spending time on the online dating website and effectively spend less time getting to know their best match.
Girls and guys lie equally when it comes to online dating profiles.
The girls who do lie on their online dating profiles will often lie about their age and weight. The guys who do lie often lie about their height and income.
This all reflects back to how things are in the real world as far as what set of qualities are considered to be the most desired for both genders.
