I was doing so good too...

My ex gf (23) broke up with me (27) about 3 months ago out of nowhere from my perspective. She never gave me much insight on why we had to end it other than saying she saw no future with me. I sent her a message a day after we broke up and I haven't talked to her since. I was doing good I felt normal I felt okay not being around her anymore even if I missed her a little but then I saw her on the street the other day. I froze I turned around and walked the opposite direction and was nervous and anxious and 1000 thoughts in my head came back "was it my fault, was my effort not enough, what did I do wrong, I miss her". I was having such a rough day because I remembered it all and it came flooding back. I messaged her on insta if we could meet up and talk. I wanted to clear the air I wanted to know why we actually broke up it drives me wild not knowing. She said sorry she wasn't interested in talking. I loved seeing her all the time and now it fills me with dread. I worry she's moved on already and I still haven't it makes me think the relationship was more one sided than I thought. I just worry she was faking it all.
