Just imagine being in a relationship with someone that takes important decisions behind your back so you don't get to have any say on it.
I'm sure it will end up with a "happy reunion", because it always does, but I just thought that he viewed this relationship as something more important than a high school fling, so if he's going to act like that now, he would do the same later if they got married.
She deserves better, and he needs to realize he can't decide on things like that without even talking to the person he's in a serious relationship with first, and then think it will all be okay.
