Is there any difference between these sentences?
"If anything happened to her, I would help her."
"If anything was to happen to her, I would help her."
"If anything is to happen to her, I will help her."
To me sound like the third sentence conveys that it is more likely to happen something to the girl than in the second or first sentence. But I can't see the difference between the first and the second sentence, besides the second one being somewhat more formal.
