Girlfriend (f29) told me I have to block and unfollow all non celebrity females on social media is this INSANE behavior?

My girlfriend has been taking my phone at night when I’m sleeping and going through blocking all females on my social media. She’s insecure because she cheated on me and thinks I’m going to do the same to her. I’ve been faithful.

It’s driving me crazy cause it’s something EVERYDAY. Today when I woke up she said for our relationship to blossom I need to block all females who aren’t celebrities on my social media accounts…. This to me is batshit insane.

Any advice on how to fix this??
