Do you think I should talk to my ex bf?

If you're not seeing or talking to anyone at the moment and the feels are there then, do what's reasonable. You both are older now so I'm sure he'll forgive you and leave the past in the past (We were all crazy ages 15-18). Just keep in mind a lot of things can happen in 3 years and people can change and that's a sword that cuts both ways. So if you think his still a good guy it's worth a shot. Just make sure he doesn't have a girlfriend, never assume he doesn't. Best thing that can happen is you get reconnected with a old fling, worst thing is maybe just some casually sex, but hey that might hold you over till you find someone better!
