Is he cheating?

Alex

So my friend Gracie has this boyfriend and I don't like him and none of our other friends do either. All of his friends are girls, he even talks to one of my best friends. Anyways, tonight I was on Snapchat and I looked at my friend Megan's story and Gracie's boyfriend was with Megan and her 3 friends getting drunk and one of Megan's friends was naked. He also turns off his location at night and leaves Gracie on read. I think he's cheating and if he hasn't he will and Gracie is so blind even though its so obvious. Maybe I'm being crazy? I dont know. I have a bad feeling Gracie is going to get her heart broken. And I can't tell Gracie that I think he is a fuckboy or whatever because she denies it because she's so in love with him. For example, in one of Megan's stories Gracie's bf was holding a beer but Gracie said he said he didn't drink it. She's in such denial!! I would have gone crazy on him at the fact that he's drinking with 4 girls and didn't tell her or invite her. 😕😒
