Yep, that's him! (They're no longer together, though, as evidenced by
one of DJB's blog posts and
her angry reply.)
I should probably mention who this lady is (since by now it's kind of obvious) - triplewipe45, who you might remember from the SuperPsyGuy callout campaign. To be honest, I feel kind of bad making fun of her, because on one hand nobody should have to go through abuse like she did... but on the other hand, she perfectly exemplifies everything wrong with Tumblr.
EDIT: Also, I noticed that DJB follows cuteosphere and her other blog dragondicks. Eww.
