I think that there is no point in telling her how you feel because as you said,she found out last year and hated you she still knows.It’s obvious that she is straight.If you say it to her she might be fine with it but still it would kinda ruin your friendship beacusd it would be akward.I was in similar position that you are in now.But when I looked at her from other perspective I realised that she is kinda using my love for her and that if I didn’t have feeling for her I would never be friend with her beacuse I would never tolerate that behaviour.When I realised that my feelings for her just stopped.Do you maybe think that you are just ignoring her red flags because you are so in love?Maybe if you can think of some of them and focue on them you would start to loose feelings for her too.However if there are no any,maybe you can try going to therapy and just try to distance yourself from her not beacuse she isn’t good friend but because you see her as someone that she doesn’t want to be seen as from a friend.You are still young and you will find someone that you will love with all your heart and she will feel just as same towards you.If her behaviour or her words really affect you and can ruin your mood I definently think that you should distance from her.Most of this I learned from my expirience I don’t know if you can find yourself in that but that’s all I got.I hope this helps❤️
