Doomed Yuri/GL irl people. Did I do the right thing?

Long context~
So me and my girl (we are not really dating) , do love each other so much . As I am a bisexual who has experience with girls before but my partner she is a total straight, she says she completely ignores my romantic feelings towards her even tho everyday she has been receiving from me is my affections. When it comes to her other love stories I often get jealous and desperate alone tho she knows it , she said it's okay as long as I'm with her even if I'm hurt being with her , saying I'm trapped with her because she has never stopped me from leaving her , but I simply couldn't. But recently (last night) I told her everything I had in mind but she said she loved me once but she didn't see the future with me and said she found someone she really like now . I asked her why would she assume everything as her own? And not giving me a chance and just to go for another straight guy , I burst out my tears and asking her why hasn't she left me alone . It's hurt when I realize she doesn't love me but she love the thought of me , my attention and how I care but even putting distance between us doesn't make any differences . I told her she is breaking me slowly pieces by pieces. She decided to leave me yesterday and now I'm so desperate I just can't stay w/o her . But I apologized to her everything I said last night , I'm so lost.. should I just keep up w her as her washing machine that she could toss all her dirty shoes . Should I really let it go..
