I'm going to push what I've written down to add this: You mention "two species", but you don't have anything written about that. What do you mean by that? This could be the clue we need to solve the mystery. It's true that any bit of information can be a big help.
SPOILERS!
She doesn't die at the end of "The Butterfly Effect". In the theatrical version, he threatens her as a child, telling her that he will kill her if she comes near him again. When he sees her as an adult, he does not talk to her. In the director's cut, he returns to his time in the womb, making sure that he is stillborn so that he will never harm anyone. Remember that, in the film, his mother says that he nearly died at birth.
The remake of "The Time Machine" does have him trying to avert his fiancee's death. That's when he decides to travel into the furture, realizing that the past can't be changed.
I can't recall a phonebooth except for the two Bill & Ted movies, and I'm sure that you couldn't mean that. I'll try to recall other time travel movies that might have that situation.
I've found these films, but I somehow doubt that these are right either:
"Timecop" (1994)
The Time Enforcement Agency is specifically formed to prevent such alterations. This causes a dilemma for the hero, Max Walker, who is charged with preventing time-travelers from altering time, but is tempted to do so himself to prevent his wife's death. He later learns that her death is the result of another's meddling with past events, allowing him to save her and their unborn child.
"Happy Accidents" (2000)
Ruby Weaver (Marisa Tomei) is weary of her long history of failed relationships with men when she meets Sam Deed (Vincent D'Onofrio) in a park. But after the two fall in love, Ruby becomes suspicious of Sam's past and under pressure from her, he finally explains that he is really from the year 2470 (what he calls a "back traveler"). Ruby initially passes this story off as yet another case of male nerdy weirdness, but after Sam's constant persistence and growing agitation, she begins to wonder and finally takes him to see her therapist (Holland Taylor). The balancing act engineered by writer/director/editor Brad Anderson throughout the movie keeps both Ruby and the audience guessing as to whether Sam is telling the truth or delusional and perhaps even becoming dangerous when he reveals that everything he has done is a deliberate attempt to change her life. The film's resolution is surprisng and self-consistent with everything which has gone before.
I haven't found anything else that matches your description. I must have missed that one.
