Maybe it was her cousin?
There’s nothing more heartbreaking than figuring out that your boyfriend or girlfriend is cheating on you. For this poor soul, he found out when his girlfriend sent a selfie that accidentally showed her boy-toy’s reflection on her computer screen. We’re guessing the boy-toy didn’t know about the original boyfriend, otherwise she would’ve told him to duck.
Or maybe the thought never occurred to her that her monitor is reflective. Kudos to this guy for having a keen eye and spotting the mysterious fellow on his girlfriend’s laptop. Now, the next step would be to gather her things and toss them onto the curb.
