Well there are other things you could do (I am not saying you should - just you could):
1. you could forgive her and accept her shortcomings if her good parts outweigh them
2.you could avoid situations where you think she will fail you
3. you could tell her you are leaving to find another who is more empathetic
(and then be prepared to leave because she won't try to talk you out of it)
4. you could tell her what you would like her to do at the time it comes up
5. you could ask her not to talk at times where she will not respond as you want = so you get to say stuff, but she can't make it worse by saying something stupid at least

I am sure there are a lot more.
