As a thoughtful starting place, don't refer to the object of your affection as a bitch; that's actually not as complimentary as conventional wisdom would have us believe. "Bitch" carries a lot of hurtful connotations that are persistent holdovers from a patriarchal society bent on keeping women down by associating anything that is inherently female with anything that is negative (someone who is weak is colloquially described as a pussy [female genitalia], while someone who is confident and dominant is colloquially described as cocky [male genitalia]). By mentally linking strong women with bitches, you simultaneously dismiss their strength and reduce their humanity by equating them with dogs; you make them immediately less than. And that's no way to get your dick wet, am I right, boys!?

Instead, maybe play around with some thoughtful nicknames that are more specific to her, a nickname that can only belong to her because it is born of your unique relationship and your intimate understanding of each other. Or if nicknames aren't really your thing, it is highly likely that she will also be fine with you referring to her by her name. "Barbara" if her name is Barbara, or "Sue" if she's the type of girl whose parents named her Sue.
But don't get hung up on nicknames, because the key here is respect, and there are a lot of other subtle ways to make your woman think you respect her. When she gets home from work, chances are she'll want to tell you about her day. The trick here is to -- and this is going to sound crazy in how simple it is -- listen to her, much in the same way you listen to your male friends or the characters you most relate to on your television. Listen and then respond thoughtfully; if you see a solution to one of her problems, offer it, but if it's clear that she'd rather just vent for the sake of venting, give her a comfortable and supportive place in which to do that. Remember what she says, too, and the specific dynamics between her and her co-workers, as this will help trick her into thinking you've been paying attention. It sounds too good to be true, but if you make sure you listen to, understand, and respect your woman for just a few several years, you will have her convinced that you actually respect her. It's that easy. Once you've fooled her into thinking you respect her as a person, step two is to just continue to do that for the rest of your lives together and then strap in, because the next station stop is East Fuckhampton, Boobsylvania, where you will be getting down with your loved one every single night, except the nights where you just sort of get tangled together and watch Netflix because one of you is feeling farty and because Orange Is the New Black is ohmygod SO GOOD.
