Can't say I'm up to speed with the Sandra Bullock issue, just saw a headline here and there. So the information I have received is from your post.
Ah! If it were only as simple as logic and common sense. Why do "good high class girls" fall for vermin? Low self-esteem. Someone with any sort of self worth would never put themselves in a situation like that. Even successful movie stars have deep seated emotional issues that need to be resolved. The source. Whatever it is.
