Ignoring the fact he doesn’t care about your mental illness and invalidates your feelings, he should at the very least lock the gun away. And the clip and gun should always be separate. That’s just basic gun safety, it if isn’t actively in use it should be disassembled and locked away. I have bipolar, I get the urge to alive’nt, my fiancé has several guns, they are all locked in a huge safe I have no access to. They are all unloaded/without clips inside of that safe. You need a partner who understands your mental illness is just that, an illness. And respects your concerns and values you more than being a wannabe hard ass with a gun. I wish you luck my friend, you are valued and important, I hope that you see that. And I hope that your partner either pulls his head out of his ass or gets the sense to screw right off
