Apparently Blink 182 split because the three band members hated each other by the end of it all...
They are back to being friends and have got over most of the bad blood now though. This is mainly due to the fact that Travis nearly died in a plane crash though - and it made them all realise that life is too short for silly grudges.
Here's what Tom DeLonge said about the band hating each other:
Although it doesn't get mentioned in interviews, the thing that killed Blink 182 is that they all went off and did their own solo projects, and that's what started the rivalry and animosity between the three friends.“We all hated each other’s guts for no reason. We don’t even know what we were fighting about. I was very open about it. I was like, I was never going to do this again. I really thought, never … I was totally fine and happy where I was. But then that plane crash happened, then you realize how stupid you’re acting and how petty things are and then I started thinking ‘Oh my God.’ I like the idea of choosing not to do it but I didn’t like the idea of God and nature choosing for me. [...] After that I was kinda open to whatever. And no one wants a heavy heart with old friends. We all hated each other’s guts for no reason. We don’t even know what we were fighting about. That’s how stupid it was.”
