Am i being such a biiiiaaatch ?

i often like guys that play hard to get and i tend to back away from guys that are really into me. I just can't help it. i hate how my mind works (or heart.. i don't really know). There's this old friend that had a crush on me when we were little and i haven't seen him in a long time, he's giving me a lot of attention and obviously shows that he likes me. I kinda felt uncomfortable and gave him some hints that Im not interested. So he just stopped and became really casual and indifferent with me. After a few days of him snobbing me, i can't get him off my head. I feel like i really do like him. BUT im not sure if i like him because he's snobbing me or because i just simply like him. I don't want to be mean to him by leading him on. He's such a nice guy and i've known him for so long. Im scared to give a hint to him that i like him because i might not like him back when he starts to like me again (I just can't control these bitchy feelings). A situation like this has happened a lot of times and im tired of it! Should i go and show that i like him?? or stop coz i might just like him coz of "the hunt"??
