I walked away from her angry it got this way.
What made you just walk away from her like that?
I can't deal with her in this mood.
Leaving your partner in the middle of a discussion without revealing your true feelings builds up resentment. Open yourself up to her and tell her about your anger so that it doesn't get bottled up inside.
I just can't with her.
Well, you need to if you want this relationship to last.
