Need help Taurus Girl Cap boy

So I started talking to this guy on the 15th. And everything was good. He was very sweet, gentleman like. We've even kissed, flirted. But I'm being to realize that I don't like him in a boyfriend sense anymore. And it sucks because I don't want to hurt his feelings, or waste anymore of his time. I can tell he is really into me. But, there's just no spark anymore.
😢 We've been on two dates one was today. After our lunch, I wanted to tell him but I decided to wait. I want to think things through and find out what I'm going to say first. How do you break things off with a guy nicely? I just turned twenty, and I'm so not used to dating. Please help.

Just tell him straight up. If possible, give a reason why. I think that sometimes, when it comes to some of us, trying to be gentle can actually have the opposite affect as it feel a bit insulting and weird. Not saying be rude, or mean......just be honest.
