The two different ending of the movie butterfly effect----电影蝴蝶效应的两个不同结局

I watched a movie The Butterfly Effect in 2005,the ending is that they meet in the street. lately,I watched this movie again,and I doubt if something wrong in my mind.Because the ending is transformed to hero suicide in womb.and some people asked this question,there are two URL,one is from Yahoo,another one from Baidu.

我在2005年看过电影蝴蝶效应，结局是男女主角在接头擦肩而过。最近，我又看了这部电影结局居然是，男主角在他母亲的子宫里把自己溺死了。令我大为吃惊。
有人曾经问过这个问题，以下两个连接分别是在雅虎和百度的提问。

下面的内容来自维基百科，我看的第一个结局，貌似是导演为了电影忠于原著而制作的，精神可佳啊。

Alternate endings
In the director's cut ending, the film ends with Evan traveling back to the day of his birth, and as a fetus, strangling himself with his umbilical cord. A voice-over replays of the fortune teller saying that he does not have a soul and was never meant to have been born and his mother saying she had miscarriages before him. The resulting time-line shows his friends and family happier without him. Another voice-over replays his mother's confession (originally heard when visiting the fortune teller earlier, saying that he was the third of three brothers, the other two having died during birth), this time altered to her telling her fourth child, now a daughter, that she survived while her three children before her did not. It then shows Evan's mother with a new husband with the daughter and Kayleigh marrying someone she met in her new life.
Another alternate ending shows Evan and Kayleigh stopping on the sidewalk when they cross paths. They introduce themselves and Evan asks her out for coffee.
Another ending is similar to the one shown in the film, except this time Evan, after hesitating, turns back and starts following Kayleigh. This ending was utilized in the film's novelization, written by James Swallow and published by Black Flame.
