That will do it every time, however, maybe Jennifer is not telling the whole story out of respect for her parents.

I like your adage a lot, it makes a lot of sense and is quite accurate. I don't recall reading about any abuse, only a lack of affection from her parents. One of her daughters was abused by one of Jennifer' husbands and Jennifer didn't believe her until much later.

That's because I don't think one can accept being loved if they don't love themself,which is a different take on the adage: "you have to love yourself before you can love someone else". I never believed that, unless it also means the aforementioned.
Was she abused as child?

She wrote an autobiography called Surving Myself and her issues go a lot deeper. Her need for love seemed to have a negative affect on herself and at least one of her kids. Still, if Hollywood held everyone up to a high psychological standard then few people would be working lol.

I share your thoughts about her beauty and career,but I there is something deeper going on. The fact that she has been married 8 times,and the incident when she shot herself in the stomach years ago; many beautiful suicides shoot themself in the stomach instead of the head for that reason. She also attempted suicide as a teenager. I don't know of Jennifer has written a bio of her life, but I can see it possibly happening.
"My need for love owned me."
