I Am Very Much In Love

Hello, about three years ago my best friend found a girlfriend. They were together for about a year and we went out together. Then she caught another and is still with him. I lost all connection with her, we didn't even say hello. Earlier this year, I enrolled in extracurricular classes and she was there. Little by little we started making friends again and going out with her company. Everything was great, I only had friendly feelings, but we started writing to each other every day and soon I fell in love with her. I also admitted my feelings, she accepted it quite normally, although she was disappointed that I was not the real friend she thought I was, but I liked her. We kept writing, I became more and more attached to her and I told her. She assured me that my feelings would stop, but on the contrary. I was very jealous when she spent time or wrote to her boyfriend. We went out with the company, but I couldn't stand it. Before I fell in love with her, I considered him a real friend, but it so happened that I hated him. Only the two of us knew about my feelings for her, but our other friends began to doubt that I liked her. I also said that I love her and will fight for her, but quite often I feel hurt and I feel super sick. It really means a lot to me, but it hurts a lot. I think all the time. My question is whether to continue my contact with her and fight or interrupt everything to forget her. but quite often I feel hurt and I feel super sick.
