Phloppy get out of the relationship now, you're doomed. Regardless of how much you think you're happy, it's not worth your time. This isn't out of some petty rage or contrived jealousy, but out of the wisdom of a guy who got to laugh his ass off as the guy who his ex girlfriend cheated on broke down in front of him as she told him that the cycle had happened again and that his "happiness" didn't cut it for her anymore. Since we're a visual culture...
