Cover art for Blame It On the Changes lyrics by Dashboard Confessional

I think it's about a relationship with both people changing and both of them going on different roads. They still have feelings for each other but are asking themselves if they should save their relationship or go on a break. The narrator (or singer) feels that they can ride out whatever phase they are going through and they have to stick together in order to do so.
