Guys, If I stop chasing him will something happen?

i have been single for 6 months, and I like this guy and he likes me too but I guess he doesn't want to pursue a relationship.

if I stop chasing him do you think something will start happening?

i know for a fact that there is no other girl because his friend would tell me because they live together.
