"I Cheated Twice, I Don't Want To Hurt My Jobless Boyfriend Again, But.."

Fellow nairalanders. I am confused please, i own a supermarket and v been in a relationship with my current bf whoz not yet working after his Nysc, we v been dating for 3 years now and it has been going well even though I v cheated on him twice, but he forgave me, hez nice. My problem now is that I v a customer, we are extremely close to the extent that we do discuss everything together. am even now closer to him than my bf, hez like a bestie.

But hez now asking me out and pple are telling me to answer him saying its advisable to date ur best friend than anyone else and I don't want to hurt my bf anymore and I don't want to hurt this guy too, he has bin nice to me...pls what's ur take on this, what do you advice i should do?
