The ignoring I mean obviously isn't when I speak to her because very few people do that. Most of the time people are polite, they talk back to anybody.
This ignoring includes - not directly looking at me. Always looking at the floor etc. Not speaking first. Not saying 'hello' or acknowledging I am there, close by. Not reacting to things I say out loud, eg jokes that everybody else laughs at. Talking to everybody else but me, even delivery men or people she doesn't know. Plus the fact there isn't a problem, for example an argument the day before.
I do that with four types of guys:
Ones that intimidate me (bosses, ones that are respected, professors, anyone better than me)
Guys that are rude to me (which would be like an agrument the day before, which is not your case)
Guys that make me uncomfortable (I get scared by people easy, so I look at the floor. For example, I was walking into Walmart, and I saw a man pull his shirt down and before he got it down I noticed he had gun in a holster tucked in his waisted band. It made me uneasy.)
And guys that I like and am afraid to screw things up with.
