I'm 20.I started dating with this girl. We went on one date. She was dressed up to nines and super attracted to me. I didn't kiss her on date as I was nervous and scared. I asked her out two times and she had an excuses. Then I didn't contact her for 10days and she reached out. We went again on coffee date but she was less enthusiastic and told me to be friends. After this I didn't reach out but she reached out two times in 10 days and I didn't call her out again because I felt rejected. After one month I called her and she was enthusiastic to hear me. She asked me to come to her restaurant where she is working. I said I will come if I have time on weekend. Then I didn't say to her that I'm coming because I wanted to surprise her. I've came with my friends and she was the waiter. She was acting cold when she saw me and didn't laugh at my jokes or anything. Day after this I texted her something flirty on whatsapp and she told me "Don't talk to me like that. I have a boyfriend". I was trying to have fun text after but she blocked me and unfriended me.
Is this over forever. I'm just sad and want to apologise to her on instagram but she blocked me on whatsapp.
