I became psychotic. I started believing I was going to save the world, and I was psychic and this friend of mine was going to fall in love with me. I was convinced she was my soulmate. Arrogant, no? Problem. Two weeks earlier she proposed to her fiancee. I felt like I kept seeing signs that she was in love with me. She clipped her toenails because I complained they were long and I was convinced that really meant something.

So I was convinced I was seeing all these signs and broke up with my girlfriend. I had liked this friend for probably 7 years. The night I broke up with my girlfriend, I went to her house. I was delusional and thought if I was there when my girlfriend got home from work, I was going to literally die.
Anyways, that night an affair started. I was convinced it was destined to be. I told her I knew she was in love with me and she was my soulmate etc etc. I told her I was a psychic and it was our destiny to be together. At first, I believe it was just an ego boost for her.
She was telling everyone the affair was in my head as a cover up for having an affair with me... It wasn't until someone caught us kissing that she fessed up. She eventually fell really hard for me. My own erotomania somehow presented the conditions for her her actually fall for me.

Anyway, since I thought I was psychic and she was my soulmate it presented pretty poor conditions for realizing I was delusional. I even spoke to a psychiatrist and he said I was fine. Since I thought I was psychic, predicted her falling for me I thought my other delusions were also real.
I eventually ended things when I realized what I was doing was wrong. I told her fiancee about the affair for the third time. A month or two ago, I dropped off a letter to my "soulmate" apologizing for exposing the affair. After I dropped off the letter, I checked her instagram and she put a bunch of "inside jokes" in the comments and even uploaded a video of our song. I thought maybe she wanted to tell me she forgave me.
The unfortunate part was that I asked her why she did this and did not respond. She blocked me and I'm sure she's telling her fiancee that I'm seeing "signs" again.

This was what I told my "soulmate's" fiancee before she fell for me. Understandably, when she started falling for me it cemented my delusions pretty securely:
