I and my ex-girlfriend were in a long distance relationship with her living in Chicago and me in Miami, we were together for a little over a year. Back in April, my ex-girlfriend called me and told me that she miscarried. I asked her how she knew that and she said that she cramped up and excreted what appeared to be a placenta (not sure what it was TBH.) This was the first time she told me she was pregnant but I gave her my condolences and that I was here for her and loved her. She said that wasn't true and I was never there for her. I asked her why she said these things and she said we were growing apart. This was the first time I ever heard her say this and had a good relationship up to that point. She finally said she wanted to "think" about staying together with me. She hung up and broke up with me over the phone the next day. I was shocked by this and initially didn't believe it. I wrote her a total of three letters asking her to not leave me in a time of need like this but she never replied back. She instead deleted me from her social media sites. We haven't spoken since. I want to have a better understanding of what happened.
