My boyfriend forgot his phone now he’s on his way too the “gym “

Y’all tell me why I see a girl name come across his phone the message said “baby are you on your way “ 😐 his phone has a lock on it and I don’t know the password to his phone but I wanna break his phone so bad 😤‼️ I’m so fed up I’ve been a great girlfriend to him 🥺 I do anything he wants ‼️ I cook , clean , massage his body , listens to all his problems & I even have sex with him when I’m not in the mood ‼️we even had a threesome I didn’t wanna do it but I did just too please him 😤 and for him to be cheating on me is fucked up 🤦🏽‍♀️ what did I do too deserve this ?
