This guy and I have been school mates since elementary school till college. We never noticed each other until college started. Since we were paired up together in a group project, we became a bit closer. I felt that he has, maybe, some feelings for me because he really cared about me when I was sick in school and I noticed that he didn’t do the same for other girls. He would occasionally steal glances at me in classes. In addition, he would stare at me when I was laughing with my friends and he would then be curious and ask me what was I discussing about with my friends.
I feel like he was always inquisitive about my life which I didn’t see him doing to other girls. My classmates joked about us being together and he would always smile and look at me. During that period of time, I didn’t dare to confess to him because both of us were preparing for national exams and I didn’t want to get distracted. After the exam, he went for his national service. I finally made a decision to open up to him and tried to message him after months of pondering. I texted him and complimented his cute profile picture (he put his baby photo on it) and took this chance to have a chat with him. During the conversation he seemed to be very interested and would text me back immediately. But then after a while told me that he needed to end this conversation because he need to sleep soon (he has to follow the rules in the national service) and will text me another day.
However, after a week, I think he deleted my number since his profile picture wasn’t showing anymore. I thought I made a wrong move. Did I scare him off or something? I’m sorry if I sound so inexperienced because I have never been in a relationship before and this is my first time falling so hard for a guy. Did he not like me at all? I don’t even know what to do now. Please advise me.
