I just laid there in bed for the entire night, bored, but I definately did not fall asleep.
I made sure to make timestamps every 30 minutes on my phone through Discord just to be sure.
I marked down every noise my cats made. One cat had jumped down from something and made a little sound at 3:18am, and one ate food relatively quietly by the bedroom door at 4:57am.

Other than that, nothing happened.
Sure enough, my wife slept from 11pm until 9am, and that morning she claimed she had woken up “at least 7 times” to open doors and from cat noises and cats jumping on her.
At this point I was pissed because she was clearly lying to me. I was exhausted and fed up with the lies, so I just bluntly called her out on it.

I told her, “That’s funny. I stayed up all night to monitor the cats, and they weren’t even in the room at all last night.
I have timestamps and everything. So you’ve been lying to me and trying to convince me to get rid of my cats? Why?” She just sat there quitly shaking and looking pissed, then got up and left without answering.

She came back hours later and ignored me whenever I talked, and when I asked her how I’m the bad-guy in this situation, she finally said that I was treating her like a child by lying about sleeping and staying up all night just to see if she was lying or not and that making timestamps and everything as if I was an investigator was “going too far” and makes me an obsessive asshole.
I did it because she was threatening to make me get rid of my cats or she’d leave me, and her claims didn’t add up.
So, am I an “obsessive asshole?”
No, your not!!!! It’s pretty pathetic
that she made up these lies. Its also obvious she doesn’t like your cats … maybe you should leave but with the fur babies!
No you aren’t. She is banking on you refusing so shebhas a way to walk away claiming she tried to make it work but you chose the cats over her. She wants out but wants to make you the bad guy so she lied about all of it and if you fell for it and did get rid of the cats she would have come up with something else. You can do better than her. Both you and your cats deserve better than her.
