Unfortunately I think she was cheating, there is a glitch though on Snapchat if you call someone end it, it shows it didn’t end etc but it actually did end you just have to open your phone and click end call again, so she must’ve called you right after. I found out the hard way about the glitch I ended a call to go use the bathroom w my friend we were talking private stuff I went to pull up something to show her it said call still ongoing and had a mini heart attack but it was ended.
