I learned that in realtionships, you cant have revenge. Because to me, trying to get even with someone only makes you become more restless and the excitement of wanting the revenge so much just turns your feeling all the way back down. When your bf or gf cheats on you. It hurts right ? I know, but to stoop down as low as he/she is just utterly stupid. To gain some one back is not to get even. But to show them that you can be so much better then him/her.
Do yourself a favour, always look on both sides of the room.
