Is AUTHOR wrong in the post ? POST : &amp;#x200B;

So I come up to be busy for 1 week due to important stuff, exams family issues and such. 

Around 1 day into that week I  try to talk to her shes obviously sleeping and then I pass out and she responds later into the afternoon, repeating until Wednesday. I find out from a good friend of hers that she went on a date with someone that I knew. Later that day I tried to call her within the week as well so I wasn't forgetting about her and such and I find out that she cheated (it was more than a date.)  so I try and push it back like nothing happened because I didn't want to instantly get into  a argument, little after that day I confront her and she was trying to act innocent and after that we got into a huge argument about me not talking to her for around a week after I told her that I wouldn't have any time to talk but I tried to call a bit but couldn't since she was sleeping. Little after that argument we broke up and continued our lives.
