Sharing Our Innermost Thoughts

I had a dream last night. My Ex-boyfriend was in it. In reality, he is getting married; he dumped me, fat-shamed me, treated me like crap. I sat beside him in the dream and cried on his shoulder, and talked about how we could have made it work. I have had two relationships till now, and I do dream about my Exs, but I never stalked them or anything. I am not even aware of what they are doing now after college. How can I be hurt about this with the same intensity? I am spending too much time thinking about them. That is why they are coming in the dreams.
