Someone help me with this situation?

This 24 year old girl was flirting with me when. I was 16. When I was 18 she went to my house for a counseling session. She then tried to sleep with me. How I know this is because when I told her I was going to get something from my room she then about 30 seconds later went inside my room and told me "your not gonna give me a tour". I didn't know what she was trying to do until my friends told me. I later said a joke that I wouldn't be with her and I don't think she took it as a joke. Once I realized that she didn't take it as a joke I confessed my feelings and she rejected and she never answers my text. She did text me first once but didn't respond when I responded. I asked her on a date and she didn't respond. Did she technically groom me? Why dosent she respond to me? Why did she reject me? Please help me out here.
