I'm going to refuse to argue with my gf
Is there a reason why you aren't going to argue with her?
I can't keep my temper under control when arguing.
It's good to step away from arguments sometimes. It's even better that you understand your limitations and know that things will only escalate if you argue with her.
It's just a few days before she breaks up with me anyway.
Stepping away from an argument before it escalates can be the smartest decision you make. Just make sure you aren't ignoring an important issue.
