A man that was hurt while innocently attacked could be attractive bearing battle scars. Think of braveheart? The man was a war leader! Romanticized extremely, unrealistically, of course, seeking revenge for his lost bride.
Now a man that had bruises because he fell while drunk and nailed his head against the wall, or provoked a bar brawl, would that cause attraction for you? Would that cause you to want to mother him? Not me!
I think the two scenarios are very different things. So I would have no problem myself with what happened to you. I would think the seed of attraction was already there, and just waiting to sprout.
Yes it's compassion, yes it's attraction. Is it an unhealthy one? I think not. I think we tend to overanalyze in this forum sometimes.
