I am 16 years of age and a female. When I was younger (before hitting puberty) I had this male friend that I would hang out with at school. I ended up moving but we found each other on social media a few years later. Our conversation is very halal, me asking about his family and studies vise versa. The problem is lately I cannot get him off my mind. I'm thinking about him many hours of the day and it's starting to disturb my life. I get aroused when I think about him although I never think sexually of him. Matter of fact I always dream about how if we ever get married I would strive to be a good wife and aim for a relationship like the prophet had with his wives. For some time I ignored it and thought "teenage hormones" but it's really disturbing me. I would be eating breakfast and think about how one day me and him could pray fajr together then have breakfast. I'm not sure what to do? I'm obviously way too young to get married and have tried to stop talking to him but nothing helps. Please tell me if I'm doing anything haram.
