You didn't lose the battle, but you won the war!
Sig, today you made the right choice. You chose to live to fight another day. Gf, child, etc. As gun owners, we need to be men and women of reason. A firearm is a tool, like a hammer or screwdriver. In good hands it does good work and in bad hands it does evil work. Unless you are FORCED to defend lives with a weapon your best defense is always retreat to safety. You can be proud of the decision you made. sounds to me like you have the basis of sound decision making to be a good father. Congrats!
