Should I still talk to her or not this the first time I've truly loved someone.

So there's this girl that I really like. The thing is I never paid any attention to her until she started to talk to me. Then I followed her on Instagram and she texted me, and from there we hit it off really well and we kept on talking back and forth. At school she kept on giving me hints to go to her, she always came by my classroom during lunch we talked about everything.

So naturally I thought she was also into me,but she said she had a boyfriend but the relationship wasn't go going so well, so I decided to shoot my shot, she rejected me.

Since then I haven't talked to her or texted her. I dont know If i should continue communicating with her or just stop which is really hard. What should  I do?
