Characters I no longer stand

 Yesterday I read a romance when the heroine was a jerk to her (very kind and nice) love interest.  Once the love interest fell into freezing water, but the heroine did nothing because she was too busy clutching her purse. She never felt any remorse about her behaviour. I skipped to the end and the heroine never changed, so I gave it up. 

I can not longer stand jerkass characters.  Give me characters who like and care about each other, who can communicate like mature adults and trust each other. My life is too short for unnecessary drama.
