For context, my ex-boyfriend’s best friend requested to follow me on IG. I accepted it and then I messaged him telling him that I hope all was well wherever he was and then he messaged me back saying “yeh my bro I’m always alguddies 😅” I then asked him if he was sure bc his emoji seemed unsure and then he said “different thoughts 😅 I’m fine”
