Idk, to me it sounded like she made him kinda unfollow.I agree with you about the communication part. Things that makes you uncomfortable should be spoken about. But I think you should always think about why it makes you uncomfortable and how reasonable you are. Oc compromises are the thing and if unfollowing helps you and your bf decided it on his own everything is fine. But OPs gf sounds like she is looking for something bad, no matter what. She seems insecure, which she should work on, not for her bf but for herself.

All this instagram stuff is making me feel old, old but kinda happy tbh. All the problems because of instagram etc sounds so unhealthy to me but what do I know? Anyways. No matter what, at least about the snooping part OP should sit his gf down like I said. Compromises are fine, but also compromises have a limit and you shouldn't accept everything just because someone is insecure. I hope I'm understandable, sometimes I wish my english would be better so that I'm sure I've written down what I wanted to say.
