Sharing Our Innermost Thoughts

So I have had a bestfriend who is very toxic and narcissistic…So initially we were just bestfriends but after sometime she caught feelings for me…Basically what happened was she tried with all her crushes and came to me when all of her crushes rejected her. I was always there for her as a bestfriend…I was kinda being used… Always forced me to tell her if I like her or not…It was purely platonic for me but she misunderstood me.Even my other guy friends asked me to get into a relationship with her because she was pretty…She kinda forced herself on to me to make me like her…So one day we went out for lunch and had funnn but she really wanted to drink that day…I don’t usually drink but have tried a few times because of peer pressure as a teen…So that day we didn’t drink at a pub but we got alcohol from a shop and took it to a random empty building terrace where she gulped down an entire bottle of vodka…I tried to stop her but couldn’t as she drank it very quickly while was on call for a few minutes .after a while she started talking to me and told she liked me because I’d never treat her like her exes or crushes…In a few minutes she said that likes me…When I didn’t react or respond much she started verbally abusing my ex.then she called herself to be prettier than my ex and verbally abused my ex…Then she was leaning on my shoulder and then she said that she knew I liked her and forcefully tried to kiss me which I rejected. Then she change it to something worse by calling me names and slapped me once I knew she was drunk so ignored it too.Now she said I know what you guys like and she tried unbuttoning my clothes and climbed up on me.She tried to touch me in a very in appropriate way tbh I felt so disgusted when she laid her hands on my crotch.She asked me to touch her and my reaction was I froze .I never anticipated that my bestfriend and I would be in such a situation. She threatened to make noise or shout if I tried to tell her to stop. But luckily she started puking immediately while she was trying to kiss me .The worst memory I have to carry is that she tried to kiss me after puking. This was a terrible experience a lot of people said there is nothing that can be done about it so I should consider it as fun but I felt extremely violated and disgusted. Thank god she started puking the alcohol out. We stayed on the random terrace while she refused to go home and I finally convinced her and had to drop her home.I spoke to her mom and told her she was at a ladies pg and got drunk there with her classmate and they couldn’t drop her due to their curfew. After this the next day she picked up a fight and we stopped talking for a while.I could understand that she was feeling rejected and was not in a good condition but that doesn’t justify her actions. I don’t understand how movies have changed the perception that seducing someone can make them fall in love…We did talk after the incident and tried to be friends like before but she wasn’t worth…letting her in and letting her to mess with my mind put me to a worse of situation. I liked her but not the way she wanted me to…There’s another very toxic thing that keeps happening which is she uses me to talk about her problems and then treat ne like trash and I have been manipulated and I was forgiving for a while but stopped recently .I just can’t tell anyone how I felt without people fantasizing about it .I feel disgusted and she is a big trigger for me the thought of her or a she trying to contact me ruins my mind and I just hate myself because I liked her .
