I want to mention that I am only 15.

My LTR lives an hour away from me and usually comes to my place on tuesdays.

She is a fat 6, and I already debated getting rid of her with myself, because I can obviously do better.

I just now cancelled her coming over tomorrow because I have something else to do, and a short conversation occured, consisting of her complaining but ultimately accepting it and saying it's okay.

I just saw her on my facebook feed commenting on a post a guy made to her wall yesterday, and posting 'Who wants to text/call?', assuming she will complain about me.

What should I do as consequence? We had a csll sheduled for this evening, should just not call and ignore her? For how long?
