You know, I'm betting this attitude shows right up front to most women. They generally steer clear of a total lack of confidence and someone that projects total loser(even if they are not, which in this case..well..). The other guy gave him the best advice, but I'm sure he'll still rely on the "nobody loves me mantra" and that is to forget about meeting someone and just enjoy life. That kind of vibrance is attractive and even if you don't meet someone, at least you've lived a good, meaningful, and fulfilling life in every other way.
As an aside, if the one believed in God, he might actually think that perhaps his life was meant to be dedicated to something else? Last I checked around the world, there are plenty of worthwhile causes out there that someone without a life could dedicate that life too. I suppose it is easier to be perpetually unhappy and miserable though.
