Search Results: when to call after first date

I started casually seeing this girl in fall of 2013. But we became exclusive in March of 2014. We were only 18 & 17 but we seemingly had an amazing bond, despite her being Mormon and me being an atheist.
We broke up in July of 2014 because she needed to marry a Mormon. Throughout the rest of 2014 and 15, I was bitter and angry. I didn't understand. But I reached out to her after a very vivid dream in November of '15, and she expressed how much she had liked me, but I hurt her by disappearing from her life after the breakup. She wanted to be friends. She told me I had no place in her life.
In June of 2016, she reached out to me and we had a 5 hour conversation on the phone. She said she felt a 'prompting' from God to reach out to me.
After a few weeks, I admitted I was in love with her and I couldn't just be her friend. Over the next month, I tried her church but it wasn't for me. She eventually said she was in love with me, and she would find a way to make it work.
In December of 16, she left and went on a mission and broke up with me on Valentine's day in 2017. We couldn't be together.
In June of 17, I sent her a letter, saying I missed her and loved her. Despite her reading it over 10 times, she only responded with conversion stories.
She returned in 2018 and she ignored any call or text. We eventually ran into each other, and she blamed the failing relationship on me and brought up things from when we first dated.
She got married a few months later.

I'm still devastated and I'm not sure her love was real.
