Oh....you are in TROUBLE !!!!! Will she understand !!!!???? Are you mad ??? NO women on earth would EVER understand such a choice. In my view, you have two options. One - get the engagement ring and put off the rifle. Two- get the rifle and forget about the engagement....if she finds out, it'll NEVER happen. Even if she is the forgiving type - she will never forget this one....and she will NEVER let you forget it, either.
