I am currently in a relationship with a man I love, without a doubt. But my ex still pops into my mind sometimes, like the other day I had to serve him at a restaurant and I was so nervous and it felt like my stomach dropped. I was really shaky around him (physically, like my hands were shaking). I’m not sure how I feel about him. And I don’t know why I feel like this. I love the man I’m with. But my ex is still in the back of my mind. What is going on and why did my body react like that when I had to serve him at the restaurant?
