Advice 🥺

My boyfriend i just got into a lil heated discussion. We were laying in the bed an another female called his phone I answered to see what she wanted and she said “Tell him to call me after he leave” so I’m asking him all these questions like why she even calling your phone I told him no female is gong to call you unless you’ve been giving them attention. So I started going through this phone and I seen a name that I’ve never seen in his phone I’m asking him who is this female he said “her number had always been in my phone” but what really made me mad is that the girl name was saved as “🥶Lightskin Bae💛”so I’m like these are new Emojis this number hasn’t been in your phone.. I told him if he couldn’t tell me the truth about who theses females were then he could leave. I know it’s like I’m assuming that he’s cheating but this isn’t the first time this has happen
