dating

so i’m going a first date with somebody sunday, i already told him i’m not looking for anything serious right now it’s just as friends but my cousin is telling me i should just give him a chance because he’s a good guy , we are only going as friends so what after i don’t have any feelings or interested should i still keep tryin until i get feelings or cut him off ? i feel like i’m not ready for sumthing real right now but i don’t wanna pass a good man by and never come across one again
