Sent really inappropriate text messages to me unwarranted.

This person messaged me last night and thought I was another girl. What happened when you talked to him?

They messaged me and knew my name. The proceeded to tell me how sorry they were for what happened with them and my fiance and they knew his name too. I said I wasn't going to reply until they told me their name and I didn't know what they were talking about and they messaged back saying they didn't sleep together she just gave him head. Dumb

texted me hi beautiful late at night
