I find it really difficult since my relationship ended in January to find peace in being single again. I'm an emotional guy, supportive and reliable, but she left me for someone that is not any of those things. I am starting to wonder if I went about things incorrectly and being a "good guy" is just not good enough. In my hurt mental part, I feel like if I don't change something radical about myself, I will just have a repeat of my failed love affair. I did everything and she still rejected me; how do I reconcile this? Hard for me to not pick myself apart and wonder if I had done this right, or that differently, if things could have been saved. I guess I'm still hung up on her.
