I can't get over my ex even after 7 years
What about the ex do you keep dwelling on?
She was an important person in my life back then.
I understand she was important, but 7 years is a long time and you should be over it by now. You need to move on with your life.
It's been so long, I feel like my ex is dead and I'm still in the grieving process.
Try to find something to take your mind off of her. Maybe watch a movie or go out and exercise.
