I bet you don't even know what it feels like. Watching your past-love holding hands with someone other than you. All you can do is quirk up the corners of your mouth and be happy for them. But when you see them pass, then you can show your true emotion: sadness. You don't want to feel it but you just do and it happens without warning. It starts out like a headache, then a migraine, and before you know it your eyes start to water with tears he doesn't deserve. I bet you don't want to feel this way but it's just "too soon", and you start to feel cold and hot at the same time. You feel light-headed and you chest grows tighter with each sharp intake of breath. I bet you don't want to feel like shit every time you look at him, you just do.
