Your GF is an orc. She is strong & odd; orc culture is different from human culture. They value strength, honor, & relationships. Orcs, while very brutish, aren’t unintelligent, they just use blunt direct language, & think in the same manner. She’s actually quite smart, for an orc at least. You’re the weaker of the couple, so by orc culture, you’re like property/a servant, but orcs love their spouses immensly nonetheless, especially yours. You & her are still adjusting to each other’s culture.
