Memories that surface

Ever feel like the memory of what someone tells you, is also the one thing that keeps you from moving on?they tell you something personal about themselves and that feels good at first when they tell you out of affection. But later, you see something they posted on twitter that leads to that memory again. So, all the feelings come rushing back. If you know to what I'm referring to, then you'll agree with me. That it really sucks doesn't it?
