How to get over him?

Beata

A long time ago, almost ten years now, I dated an incredibly wonderful man. We were together for about two years. He was kind, sweet, and loving. Of course, not everything was perfect, but to me, he was. We lived relatively close to each other, but then I had to move to another country. I didn’t want to, but I had no choice. He said he would come to visit me and we will make it work, but I knew it was his dream to stay where we met—America versus Europe. So, I stopped talking to him and eventually asked him to let me go. And he did. He never came to visit me.

Since then, I haven’t been able to find anyone else. There’s always something wrong, and I keep thinking about him, comparing every new person to him. I want to let myself love again, but I don’t know how. Do you have any advice? I really want to move on, to stop comparing him to everyone I meet, and to stop thinking about him.
