So I need some girl advice I texted a coworker the other day cause his dad was in the hospital and I felt bad so I wanted to see how he was doing he said everything was fine so he texted me again later that night seeing if I was awake and wanted to know if I wanted to get a drink with him and if he could come over and I said no because I just put my daughter asleep and my man proble wouldn't want you over so he called me sweetheart yesterday in a text I work with this guy so I don't want things to be awkward does it sound like he's flirting FYI he has a girlfriend
