Well! Disrespect comes in Various Forms ! I don't suggest u act all angry or argue over it! And it depends, if its her first time! There is a possibility she may not be aware and even if she is , she may be going through a lot u aren't aware of ! So I will suggest u address it by talking to her even when she still acts up be Patient cos she may of have not snap out of it I mean whats she's going through! But just let her know! Even if she doesn't apologize don't try to punish her especially giving her too much space and not checking on her! It would be cool u still draw closer to her and let her know that worse things are to be expected and that nothing's change and that u forgive her ! Trust me she will come to her senses and apologize! And also u should understand that u also gonna mess up someday ! Its possible so don't act up or all angry! We humans after all! Ur situation might be different from others ! So be very mindful
