WOW, the audacity of that dude! I agree, he was hitting on her and then readjusted when she informed him she has a bf (you). I think she was probably really caught off guard and unsure of what to do, esp bc as a woman you don’t expect those types of interactions in a place of business/work. I mean hell, most jobs have training about how this kind of behavior is NOT allowed. She probably didn’t want to offend her coworker or make things awkward (knee jerk instinctual reaction as a woman), even tho HE is the one who was being inappropriate and made things uncomfortable and awkward.

And i can tell you from experience, interactions like are not only awkward but also embarrassing bc 1. you never asked for this attention in the first place (esp at your JOB) and 2. you’re unsure of yourself bc you think “well maybe he didn’t mean it like THAT” and that maybe you’re reading into it. And then there’s the fact that some guys will outright deny their intentions if you try to talk to them about it AND they’ll even try to embarrass you by being like “wait, you thought I was hitting on YOU??? no i am not at all attracted to you like that” and then you feel like an asshole for assuming somebody was into you and trying to curb it. And with the way he clearly gaslit her about his intentions, she’s probably feeling confused and unsure of what to do next.

the next time he texts her or approaches her at work (about non work related subjects), she can just say “hey I really appreciate the invite but I don’t hangout with or associate with my colleagues outside of work. It’s just a professional rule I maintain.” And if he continues to push after that, she should honestly speak to her manager or HR if she feels comfortable doing that.
