This interested man sounds like he's just understandably, humanly obsessed with this father's daughter. The capability of this man matches well enough with the father's daughter. The only way father's daughter will learn is to let her experience. No more holding her back. She has this possibly once in a lifetime opportunity and you're just going to take it away from her? Even if it doesn't work out for her on her own terms, the experience can encourage her to improve her cognitive ability so that she is more eligible for people you consider more worthy.
