How do you let go of someone who was never really yours?

for the past 5 months or so I was cheating on my boyfriend with this guy who was also dating someone... when I started hooking up with him I thought we might have really had a chance to try things out, because we got along really well and have a lot in common... but when I realized I was wasting my time with him I told him we couldn't hang out anymore because what we were doing wasn't fair. but now I just can't stop thinking about him when I know that I need to because it is the right thing to do... I just feel really sad, and kind of used, and its like it's so easy for him to forget about me... how can I do the same? I was just wondering if there might be some ways to get him out of my thoughts, permanently...? How can you let go of someone who was technically never really yours...?
