I was giving my bf a blowjob, then someone messaged my phone and he picked it up to look but then he started going to instagram, he then went to his friends instagram ( she’s a girl ), and clicked and looked at her picture. I then broke up with him. I’m thinking he was trying to imagine the girl, do you think I’m right? When I asked if he was looking at another girl he denied it and closed the app, then I looked at my phone and he was. He wasn’t talking at first then I went outside and he came after me and said it was just something random and he wasn’t doing what I think he was
