<human>: Can you provide a brief overview of the text?

She broke up with me several months ago and I've been having a hard time since (first love, was making plans to propose next year, immediate cause of breakup was kinda my fault though we were on the rocks anyway). I've been doing NC and the last couple of weeks I finally felt like my old self again. Just yesterday, a friend told me that my ex is seeing someone new (he saw a relationship change fb post). He thought it would be best to hear it from him than later on from someone else or if I bumped into her. I've been feeling like shit since yesterday (I told my friend to never tell me about her again.) My heart hurts again. It doesn't make any rational sense to me why I feel like this again. Obviously she would find someone else...
