I disagree with Laura, there’s nothing “naturally” about her behaviour and we can blame her. What she’s doing is not OK. You’re not a convicted cheater. Even if you were, this would not be reasonable.

If a guy told his girlfriend, “I need you to stop talking to your friends because I don’t trust you with other guys,” we’d have no difficulty seeing that as a red flag for abuse: isolating her and controlling her. That’s what this is. It makes no difference that she’s a woman.

And here’s a sad thought to chew on: you’re not really helping her, running around and fixing everything. You may just end up making her more dependent and insecure, even if what you’re trying to do is the opposite.
