So back in September me and my boyfriend began dating. Everything was fine until last week, when a girl let me know my boyfriend had posted a story asking if anyone wanted to play IOS games. (He always does this and it gets me mad sometimes because he’ll post that and not respond to my texts u too later) So she asked for his number to play the games and once she gave him the number he responded with “Damn yo cute ass just answered”. Immediately I thought the worst I mean how could that be a mistake right? Well then he said, “no that wasn’t me it was my friend he had my phone” and yes his friend has taken his phone before and even texted me before. But my boyfriend always said “hey sorry that wasn’t me” and this time when he was texting the girl he didn’t say sorry. He also said “I was gonna tell you hutI thought it wasn’t that big of a deal” I didn’t want to believe the situation so I kinda shrugged it off and forgave him. We ended up I guess you could say sexting after we made up. (tbh idk wtf I was doing at the time I was in denial) In his last relationship he got cheated on so I feel like he wouldn’t do that to me. Then every time we talk seriously he says “ I would never do that you’re the best girl I’ve ever had” But even despite all the sweet nothings I can’t forget the situation. It’s been almost two weeks since this incident I can’t seem to shrug it off and I feel like I’m getting played what should I do?
