My fiance started to have a problem with me owning a gun about 2 years after we were together, and a year after we were engaged.
I've been an avid shooter of friends firearms, but never had a chance to get one myself until a scare caused me to get my own firearm and CPL.
I since started carrying everywhere I go, and she originally gave me a blast of crap for it. I told her to shut up or walk out.
She still grumbles sometimes. ('Do you REALLY need your gun and an extra magazine to go to the damn grocery store? Seriously?') etc. However, she's yet to walk, and we're to be married in 3 months.
They'll learn to adapt if they're into you, simple enough.. if they want to walk, let them.
Kinda reminds me of this sign, if you get my drift.
My neighbor is for Gun Control and does not have any guns in his home. I hearby vow not to assist in the protection of his family and property with the Guns that are here legally in my home. I respect his right to not defend his family.
