My take on the situation is this..
I adore Angie, I fell in love with her when she was in Girl, Interrupted. and have "followed" her career since. I have also been mighty impressed by the changes she has made in her personal life. Her own father said she was sick and needed help and at the time, I agreed with him.. This was during the time she was with Billy-Bob.
But I think she had just been searching for something to fufill her and then she found her children. She is a grown up woman now, no matter the "mistakes" she made before, she learned from them and has become someone we should admire.
Although I think it would have been nice if they used a condom for a bit longer to spare some peoples feelings (not only Jennifer but Brad's religious parents as well) I think they are truley in love and are GOOD for one another. May God bless them and their little family!
