Pseudo Relationship

I like this guy who is 29 and I am almost 19. well the thing is, i've been talking to this one guy fr three years now. We've been in a pseudo relationship for a year now and he is already been taken. I always like him ever since we started talking. I know that what im doing is wrong because of the fact that he is already in a relationship, but everytime i think about stop talking to him, i find myself missing him. I don't know if I should just force myself to stop or just follow what my heart says. Yet I don't want him to cheat on his girl because i know how it feels like to be cheated on... HELPP :(
