KGirl - one year later con't

[KGirl]

Well, if I needed proof that my H was a f***ing idiot, I think I got it via today's hour+ phone conversation re: finances and D logistics. Among the gems were:

H (while waiting for a website to load): So do you watch the bachelor?
Me: No, I don't need any more drama and stress in my life.
H: Well, I don't have any drama.

H: So I should check the box that you want to change your last name back?
Me: Yes.
H: Are you sure? 'Cause [lastname] is a pretty cool name.

H: Well, when you go get the phone plans changed I hope you don't do anything like shut off my phone.
Me *jokingly*: that's an idea...
H: 'Cause that would be pretty rude.
Me *thinking of how rude HE has been the past year*: I don't know what to say to that, so I think it's time for me to go.

WTF?

I mean, how can it be that supposedly he took our marriage "seriously" and meant his vows and cares about me, and yet can be so glib and cavalier about his impending D? I can't help but feel like none of it was ever serious or real to him.
