I am silently angry at my girlfriend because she daydreams and zones out.
Why do you feel so angry at your girlfriend?
I feel like punching her in the face when ever she's acting like that, I make sarcastic comments when she does it sometimes.
You need to be more patient, kind and considerate towards your girlfriend when she is experiencing issues. She apparently has things on her mind and you are not behaving in an understanding wy.
Maybe you're right. I'll see who's right and who's wrong.
I am glad you are at least concerned for her feeling's. Let her know that you care and want to listen to her troubles. She might open up and then you can demonstrate your consideration towards her.
