It depends on how you define "love". Other than misgendering you, she seems to treat you well enough based on what you said.
To me, love is putting someone else's needs above your own. And it's not a binary thing--someone can generally love someone but still do unloving things at times. Misgendering you certainly is not loving, but if she otherwise treats you with respect and affection... well, it's kinda for you to decide. And depending on where she's coming from, she may even have good intentions, even when misgendering you (as twisted as that may seem). This doesn't excuse her behavior, but it may change how you view her.
The more practical question is whether you want to continue a relationship with her, assuming she continues to misgender you. And again, that's for you to decide.
