i would dump her. thats a huge red flag. next it will be "we're still friends..." ... "oh sure, he calls all the time, but it doesn't mean anything"... "we just had lunch together.. thats all" etc.
then it just goes downhill from there. he is going to continue to try to fuck her every chance he gets because thats what guys do and you know right out of the gate that she isn't too opposed to that idea.
