Is it normal to be upset that gf cancelled plans to go out with mean friend?
Today me and my girlfriend were supposed to go out somewhere. Early on in the day one of her friends asked to hang out, so she decided to cancel the plans we had. What makes this worse is that my girlfriend got mad at me for simply talking to her, citing that the friend is cruel (she is) to her and didn't want me to become friends with someone who is pretty much abusive towards her. Yet it makes this whole situation worse because she dropped our plans for someone who is horrible to her - and that my girlfriend has gotten mad at me for simply talking to as a result of that abuse.
Is it normal to be upset that my girlfriend cancelled our plans (albeit plans that were made the day before and it wasn't anything romantic, just more like hanging out) in favor of hanging out with a friend who she doesn't seem to like (she has explicitly told me that this person isn't her friend)?
Edit: I will not leave her. We've been together for a long while and our relationship is truly great. I couldn't imagine leaving her.
