WTF at people on here acting like "You should just be nice to him! You overreacted!"
A dude she barely knows comes basically out of the gate with outright sexual advances (some of you don't seem to realize that this is straight up disrespectful) and it's her job to be respectful to him? This isn't just a case of "OMG see girls can't handle a dude that's interested in them". Anything she says to him after the fact, he deserves.
That being said TC at this point you should just block him.
Prob shouldn't be giving your number to people you barely know.
