My wife bombs on me all the time when she’s pissed at me. Never kicked me in nuts though, jesus. She can’t really hurt me with punches so I just let her blow some steam. When she’s done, I either yell at her for getting physical or I apologize for whatever I did. That puts an end to the fight and we go back to normal. It is easier than arguing for hours.
Your gf would hate me. I sleep with earphones in about 3-4 now nights a week. Nothing puts me to sleep like listening to Science videos, Ancient history videos, or Space videos.
