Have you ever wondered if your girlfriend is cheating on you or flirting with other boys. Well the main step is to send in a spy to spy on your girl. DUUHHH !! or just see if she really into to you.For example hold her hand in public and see if she pulls back or kiss and flirt with her in front of her friends and see if she gets embarrassed or really red. Or Maybe even talk to her and tell her how you feel and if she looks away then shes not into you anymore then she was before. Just find a new girl that treats like a prince.
