To be honest reading that review she left him I find it a bit worrying that she highlighted this
btw from being the nicest guy he end up shaking of being nervous
It shouldn't be a bad thing that the guy is very nervous in my opinion. It should I would say be a compliment to her that the guy was nervous as he obviously therefore is saying he finds her attractive.
At the very worst you could argue she was not putting him at ease to relieve those nerves. But that again goes towards her not him.
