should I give up?

My boyfriend (7-1-85) and I broke up about three months ago and there was a chance that we were going to get back together. Lately it seems like he just really isn't interested in getting back together but then again, he's a very complicated person and it's hard to tell what he's feeling because he doesn't really show it much, let alone say what he's feeling. I've asked him a few times if there was even a chance of us getting back together because i don't want to waste my time if there's not but he dodges the question every time. Should I just give up and not waste my time? Is it too soon to tell? Will we get back together or is there even a chance? Thanks so much for your help!
