Hi new here, its a bit long winded but, a few weeks ago my partner started acting strange phone on silent never using it around me it was constantly going off that he'd get a message and he'd never look, so I looked through it and he was messaging my sister using 😘 throughout all the messages I asked him about it thinking he'd change the name as him and my sister talk but not like that but it was actually my sister he was talking to, I was expecting him to shout or something cause I'd literally just accused him and with my sister and he laughed it, anyway they are still messaging and I don't know really what to believe.
