My now ex-boyfriend cheated on me and left me for this woman. It took me some time, but I’m not mad at him anymore because he himself was so confused and so stressed out at the time with fear of a new job, unknown future, ect. However, I was in our college choir with this woman and she is known to sleep around and cheat and is a major drug addict. I know my ex deserves so much better, and even though I’m over him, I’m not over the fact that he’s dating a girl that could ruin his life. He deserves happiness and respect and someone so much better than her. I’m not sure what to do to make him see this before he falls in to deep and gets hurt.
