Oooh !! I got this one. She's definitely going to be super nervous and self conscious about the whole crutches thing so try to make her feel as comfortable as possible. Woman love romance but if you go to hard she will feel overwhelmed. Take her to get some food first. Get her some flowers, open the doors for her, pull out her chair and when you've sat down compliment her on how beautiful she is. Don't ask To many super personal questions yet. At some point during the evening (given she's not disrespectful or rude) tell her about how much your enjoying yourself. Try to be as gentleman as possible. If it goes well, then comes second date ! Please update later
