Would you date someone until you find someone better?

Dating a guy who I used to be friends with until I find someone better. I'm going away this April for a few months abroad and he knows this. But kind of feel like I'm just using him for the time being.

We fancy each other and as awful as it sounds. But is it that bad? Feel a bit guilty. He thinks I'm the one. But I want to spend my early 20s finding out the type of guy that I'm into and don't expect any relationships in my early 20s to end up in marriage. He's a nice guy but going to break up with him before I go away. What you date someone until you find someone better matched to you?

Wow big reaction! Didn't expect this.
Surprised at how 'awful' some people people think I am LOL. Sure many of you have dated casually at some point. Bear in mind I'm only 21 and I'm going to make mistakes.
Still fancy the guy and care about him. Though it was probably quite selfish of me. I have no intention in hurting him, and decided to break up. Were still friends and on good terms.
Thanks to everyone for answering! <3
