Will he come around?

Hi Fluther! I am in a situation in which I have no idea what to do. 3 months ago my best friend confessed he was in love with me. I turned him down because I decided to give my ex of over a year a second chance. I had feelings for him at the time. My ex and I didn’t work out, and broke up one month after reconciling. Now, I realize I have feelings also for my best friend. However, now he is acting “hard to get” as he said I broke his heart when I rejected him and he needs time. Will he come around and give us a chance?!
