Why Does Angel Leave Buffy?

Answer 1

Angel left Buffy for a few reasons, but they all center around the fact that he is a vampire and she is not. 1) He has no ability to give her a normal life, including children and simply being able to go out in the daytime. 2) He canot make love to her or else he will lose his soul. 3) He is immortal and she is not. Eventually, she will become old and he will be the same. As Mayor Wilkins (the main antagonist of Season 3) said, his eternal youth caused his lover to grow hateful and jealous of him. Basically, Angel left Buffy because he felt that being with her was selfish on his part and that it kept her from being with someone that countered the three reasons above. He truly loved her, so he did what was ultimately best for her.

Answer 2

It's really complicated as most relationships are but pretty much because if Angel was ever to experience complete 'happiness' the curse that gives him his soul would break and he would become the menacing vampire he once was. Which of course happened in Buffy. But it is also because he can't give her what she needs, as a human. There was one episode in Angel where he became human and Buffy and him were together and it was all perfect until Angel realised that he was now a liability to Buffy and could get her in danger because he couldn't really defend himself or the people of LA. So he was turned back into a vampire. It's depressing because they never really stopped loving each other.

Answer 3

They break up a couple of times but the last one was in the ending of season three, when Angel goes to L.A. That's where the spin-off series 'Angel' starts.
