Soooo I've never done this so bear with my here k? Ok here we go.My girlfriend has cheated on me...twice now. And before you ask how I know, she told me. Right after each time. The first time she was crying, calling herself a terrible person, saying how sorry she was, saying she'd never do it again (even though she said she'd never do it in the first place) hoping I could forgive her blah blah...
