What else can I do to get over him?

So I dated this guy only for two months, but the breakup really fucked me up. It was long and painful, I'm trying my hardest to forget him by keeping myself busy. I've started working out and am working on a webcomic now. The initial breakup happened 8 months ago and I'm still not over it. I know there's no point and we won't ever get back together, I don't even want that, considering he's been playing mind games and told my sister he'd defo hook up with her, not wanting to go into detail. I finally stood my ground told him not to contact me anymore.
Any ideas or words of encouragement? I'm tired of feeling this way...
