I dont get why tom delonge did this...?

OMG im so happy their back together. im actually gonna see blink-182 in june next year! i couldnt be happier! i totally agree that tom changed SO much, he used to be so free and he had the who cares attitude. all i know is that they didnt actually break up they were on hiatus because tom wanted to spend more time with his family, thats probably why he changed, you know like disciplining kids you have to be mature and all so it probably just stuck with him x
