Is it normal to think this way about my friend?

Hey guys. My story is a little complicated. I've known my best friend for 5 years, since the first moment that I meet her I felt something. It was nothing serious but with the time we became closer, we shared every little secret. She always knew that i had feeling for her but i didn't tell her. One day we were in her room, we were listening to music, and in one way to another i just know that she hugged me, but as my feeling for her, i started kissing her neck and then i kissed her lips, it was a long kiss. When we stopped kissing we didn't tell anything to each other, we started texting. Nothing else happened for 2 months and we felt the same as friends, we didn't even talk about it. One night we were in my room watching a movie, but then we kissed again and it became intense, but we didn't have sex. Two more months and we didn't talk about it. Another night in my room watching a movie, i started touching her, we kissed and it became even more intense, we were almost having sex, but we stopped and my feeling for her became strong and i knew i was in love, and she wasn't. Then she had a boyfriend for 2 years and me too, I had a girlfriend but we still talked during the time. And as today's date we broke up with our partners so we are starting seeing each other again, the thing is that i don't know what is going on but every time I'm with her I feel something, and I want to be with her. She came over to watch a movie last night but nothing happened, I didn't try anything. I don't know what to do, I think I'm going to wait. What do you think?
