I was going to say like others that this sounds like just being a compassionate, caring person. But when you described that you felt like you were attracted to him now bc he was injured and you could be the helper, you're right that that doesn't sound totally normal. And I say that being someone who early in my r/s with my now AH sat across from him at a restaurant and thought "oh he's had such a rough life... I want to love him enough to make it better". So, good for you for recognizing your thinking/feeling patterns.
