How to cut off emotions for a someone

ok, i have no idea how this section is different from AGNST section, so for the time being, i'll just post this thread here so pardon me if i misplaced this thread.

newayz, here's the story, i started liking my friend's girlfriend, whos also my friend, which is a really bad thing, newayz, i stupidly told my friend and the girl about it, which resulted in a really awkward and painful time for all three of us. Then i set the plan to never see her again, and started avoiding her. I kept it up for like 5 days, and then i realized that i dont even like her nemore, so yea, the way for me to end feelings for someone, would be to completely not see them for a few days, then you'll realize that you're able to live on without them, newayz, we're back to being good friends now, but i curious as to what other people would do, to "forget" someone or to cut off feelings for someone.

Jam it back in, in the dark.
