So today on my boyfriends phone I went onto the Facebook log in page. In the email section, there was an email I hadn't seen before. I automatically thought he had made a new Facebook behind my back. And started accusing him. It's obvious if he's got a Facebook behind my back, that he's cheating on it. Something in his face told me he was guilty, he looked nervous. He explained that it was an old Facebook I asked the password to before, and the email is still on there from when he was trying to log in to get me the password back. Then his dad pulled up, (he was coming to get him so he could help him with something) and he couldn't wait to get out. He promised he was coming back but then text me on his dads phone to say he's going to go home. I put the message below. I don't know what to think of this. I don't know if he has got this new Facebook and cheating on me, or if I'm wrong. I don't know if he didn't come back because he was guilty, or because of how mad I get over things. He still hasn't gotten home yet so I haven't spoke to him yet. Should I give him a chance and believe him seeing as I haven't got proof? Or is this a big red flag? Also, I tried searching for the Facebook linked to the email on a made up account and no Facebook came up..
