Most Helpful Guy
Well, you are actually right. Yes, a shy guy is highly unlikely to make a move no matter how much he likes the girl. I would say it's a shy guy's incapacity to do so, shy guys are not good at taking initiatives and making the first move. That's a typical shy guy's quality.
Secondly it's very much possible that a shy guy will have a doubt if the girl really likes him or not, or he may wonder as to how can a girl like him and so on and due to this reason also he may not make a move.
Hence while dealing with a shy guy the woman needs to take the initiative and make the first move. It shouldn't really matter if she likes him as well.1
