Am I wrong for deciding to yell at my girlfriend?
Are you really going to yell at her?
Yes I am; I'm going to shout at her and hurt her feelings.
You will come off as an uncaring partner if you shout at your girlfriend. You need to break up if you just want to abuse her.
I wouldn't abuse her even if I wanted to.
If you are making the choice to not be verbally abuse to her, that is great. You should always try to express yourself without hurting your partner.
