I miss her so much

she and i agreed to go no contact over the phone as we broke up basically for the 2nd time and it’s been 3 months, our relationship was perfect and maybe i was moving too fast and expecting too much but she said i was so loving and caring and the best thing ever now she’s going through things in her personal life and has decided it’s not right for her to be in a relationship i find myself confused because she said i didn’t do anything wrong.
