Lost with no way back

I met this guy on the internet and he turned out to be the same religion as me and same ages and amazingly cute and funny. He liked me and I liked him back, we dated for a month long distance then I broke up with him because I thought I was hurting him. Now that he is gone I miss him everyday and the worst thing is...I think he is falling for my close cousin. I am not jealous but she is my cousin...I think I still like him.
