But when I went to his messager I click this person it ask Wyd idk if it came Frm him or her ion know if it was a Chick cause it didn't have a profile picture so he reach for his phone I damn near fliped him 😒 yes ladies it got real lol 😂😂😂but he was like let me show you so he went to his messages on his phone & showed me I still really didn't see nun but someone ask Wyd I throw his phone to him & told him get out my face cause he's cheating on me ... He say how you know the number for me well '' he's right I don't know the number wasn't saved in his phone & his cousin uses his phone all the time even in front me .but then he said you mean to tell me you don't have no guy friends who you been texting I said no cause let's be real they gone wanna fuck so why set myself up for some like that he say ok ...😒😒 he gets a slap 👋🏽I told him look if you don't wanna be with me then let me go I'll be sad but I'll be ok he said ok I was texting someone but they don't live down here I said ion care if they live in Pakistan you wouldn't want me to do it to you.  he said it's not like I'm sleeping with them & looks me in my eyes & said  I'm not cheating on you ....
