I do admit that I was pushing her away towards the last few months of the relationship because I saw the red flags and I didn't want to admit it nor did I even want to confront her about it because of the pain involved with finding out your significant other perpetrated the ultimate betrayal on you. I was deluded into thinking that pushing her away was a solution to anything. I had seen the red flags and bottled up all the feelings of resentment, anger, and absolute hatred for what she did the first time and got angry at her for the littlest things to the point where I became irritable around her. I did not feel like myself at all and I feel I should have communicated more with her, but I also am not excusing what she did at all. Even through all the resentment and anger I had for her I still managed to stay loyal to her even though I could have done exactly what she did and got another relationship with the girl I'm with now on a whim. It kills me to know that I could have prevented this, but it also kills me to know that she would even resort to this again. This is not the solution to when a relationship or life gets stressful and I hope she learns that in the future.
