He left... when I loved him the most

Me and my (ex)boyfriend live in different countries and he’s in school and working. He says that he doesn’t have time for me and that I’m distracting him. So he decides to leave out of nowhere. I told him we could work things out. That our relationship could work as long as we tried. But he decided to leave. I feel so empty inside. I had our life planned out, this time I was sure he was the one, I was sure were going to get married, I was sure he was going to be the father of my kids. I was so prepared to give him everything! And he decides to leave. 💔
