I Installed a Secret Camera After My MIL Insisted on Having Our Key

My husband gave his mother our house key without asking me, shattering my sense of privacy. She’d let herself in unannounced, rearranging things or leaving “surprise” gifts. I felt violated in my own home. When I confronted him, he brushed it off, saying, “She’s just trying to help.” I was stunned—our trust felt broken. His mother’s overbearing presence intensified, and I sensed she was testing boundaries. I calmly told her to return the key, explaining our need for privacy, but she laughed it off. My husband sided with her, leaving me feeling betrayed. Now, I’m questioning our marriage. Should I serve him papers and leave?
