The Author is not able to commit to loving one female, as he always feels there is someone better and more attractive for him elsewhere. This condition was caused by a childhood of watching internet pornography, where men can seemingly have their fill of women, and a recently enhanced ego caused by the success of his internet web-comic.
Not to mention the fact that all (male) geeks have some ideal Weird Science-y super woman that they wish they could build in their basement, but can’t, so they expect their girlfriends to be said Kelly LeBrock. And when they’re not, the geeks want to dump them but would rather not face the indeterminate amount of time before someone condescends to dating them again, so they just hang on and on acting like total tools until their girlfriends stop wondering what the hell is wrong and just dump their stupid asses already.
Or, you know, so I hear.
