We both love each other but she wants to move on

Im 26m and we’ve both been together for 6 years. I’ve been cheated on before and I have lost interest in love, until I met this woman, we began our relationship as long distance which we then met after couple months. I was not ready to enter this relationship because I have plenty issues mentally when I met her but I couldn’t help it, she showed the kind of love I’ve never felt and I have very loving parents. She didn’t come from much but she worked really hard and made me the centre of her life, bought me everything I liked and notices all the pain I have whether physically or mentally. She would notice me having backache and insist on massaging me for hours or massage my head for hours if she knew I had a slight headache. She is the total opposite of me, she very shy, quiet, studious. She doesn’t have any bad habits, in fact doesn’t even see her friends or talk much, doesn’t go out anywhere without me. She just gives me her everything, yet a girl like that would go out of her way to buy me rolling papers and cigarettes, and manage such a violent depressive person like me. She’s done too much, but I took her for granted, and now she says she doesn’t want to see me. She is very fearful of me she says. She mentions being scared to see me but today she said partly scared that she might want me back. She wants to move on because I’ve hurt her way too much, but we’ve had a lot of good moments together, she’s so precious to me. This kind of fights have happened before but the difference is usually she fixes it and I got used to that, I took too long without seeing her and she has given up. I have don’t want to surprise visit her or call her, she just unblocked me and im trying to be as understanding as I can. What can I do to win her back? I really believe I won’t ever find another woman like her. Also, my entire family hates me for ruining this with her, she has met the family and relatives multiple times. We were going to get married next year and now everything has ended. What can I do ?
