I Won't Let My Brother-In-Law Use My Home Gym Anymore

I spent $12,000 building a home gym in my garage — power rack, barbells, cable machine, the works. My brother-in-law Trevor asked to use it since he "doesn't want to pay for a gym membership." I said sure, with rules: put weights back, wipe equipment, don't use it past 10pm (garage is under the bedroom). He broke all three rules within a week. He left 45lb plates on the bar, left sweat on the bench, and was deadlifting at 11:30pm. I revoked access. Now Trevor is telling the whole family I'm selfish and "hoarding equipment." My wife says I should give him one more chance. I say my gym, my rules, and he already had his chance. Trevor can pay $30/month for a real gym like everyone else.
