oh i'm noticed it very much that his word are insulting, but for me that not a reason to hit someone, maybe you can asking him to saying all of that nonsense first,
then after that "maybe asking for his advise (because he clearly smarter than you even if he lack of ambition), but it's was different story if the other people say all of that to hurt you (really mean to attack you verbally and you already warn him)".

and "she sees him as a rival" and this is my responses to that "sometimes you still need to remember there are some other people who better than you, you just need to accept it", ok i get it now, she is not jealous but she is just forcing her ideal in to MC, but because he is not, she hit him
