Not saying to be rude towards her, but do you have to engage in a convo with her about non-work related topics?

I understand why you feel how you feel. Sometimes, I get annoyed when I talk to some women at work and they will randomly bring up their boyfriend or husband as if to remind me that they are spoken for...seems like some women swear that every man on earth wanna hump them when that certainly isn’t the case...

If I were you, I would cut the convos short or see if you can find another cubicle or desk to do your work. If that isn’t possible, then try to talk about work related stuff or si ply tell her how you really feel, in a respectful manner. Sounds like she is an older non-Black woman, so she probably real sensitive and prone to tell on you st the drop of a hat.
