All these may be things to think about and work on if they are true, on the other hand HE might need a dating coach to explain that girls are “girly” and boys should be “manly”. A boy cannot expect a girl to act like his chavrusah and should understand that girls will behave differently than their friends do.
So you might have to review the date and see if there were things you did or if there is something about you naturally that would give off a particular “girly” or immature vibe. If it is true then you can thank him for being honest so you can work on the areas that need improvement in order to help you for future shidduchim. If he is off the mark, then just chalk it up to a mismatch and move on. Don’t let it get to you.
