Thanks for the answer. For me this is a sign of weakness. It forces to humiliate yourself asking for explainations she is supposed to give, even better... explainations for a behaviour she is not supposed to have. Her explanation should be due to me.
strikes me as concerning. Talking with someone to try to understand them better should not be humiliating. We are all different people, there is little to nothing that we innately know about each other. I am not aware of any duty we automatically have regarding explanations of social media accounts. Ideally, romantic partners would be able to talk things over calmly and rationally. But not everybody is always calm and rational.
I find when trying to talk with people about things they are uneasy about, it helps to come into the conversation with a very calm perspective. If you come into the conversation with feelings of hurt that she has shut you out of this part of her life like this on the forefront of your mind, that will quickly put her on the defensive and things will escalate.
I'll admit, I'm a bit autistic. But in this case, it allows me a bit of perspective that you might not have, because I can close my eyes, but I can't close my ears to the sounds around me. I have heard so many public relationship fights that started with the guy saying that his
woman owed him something less than a minute before they met up. That never goes well.
But when the guy is talking about finding out how his
lady is doing and hoping she's doing well, just before they meet - those conversations tend to go much better. But it's not just about the difference in the choice of words, it's about the difference in respect behind them.
If someone I was dating was talking about how I owed her stuff with her friends when we were having a relationship disagreement, I don't think that I'd respond to that very kindly. I'm pretty sure she wouldn't either if those situations were reversed.
I would recommend adjusting your attitude to be more respectful of her, and to understand better that she's a distinct entity that you will never fully understand. But unlike most such entities, she's been gracious enough to give you a chance to. The differences between us are amazing and wonderful. Talk to her from the perspective of trying to work out such a marvel, and I feel you will find that it's easier to talk with her than before.
I'd also like to comment that your other question may be more related to what's going on here than you might think. That sounds like a situation that would tend to get somebody very angry. It could be that she's seen that anger in you, and is worried about it getting misdirected onto her. I would like to think such things don't happen... but I'm autistic and cannot shut off my ears. I know better.
