Should I not send this letter to her parents and friends?

Hey folks, I wrote this letter. Can you share your honest unbiased views on whether I shoudn't share this with her parents and friends? I am not in contact with her or her connections and don't intend to do so going forward.

Hello,

I want to lay out the timeline of what happened between <cheater> and me. We met in September 2022 and developed a close friendship over the following two months, with a romantic undertone that was confusing, since she was in a relationship with Mr. <partner1> at the time.

2023

When her stance became clear, I expressed my disinterest in being part of infidelity. The next day, I was informed that she had broken up. This turned out to be a lie as the partner hadn't been notified and she was still involved with and cheating on him. A while later, I was again apprised that that relationship had been dissolved.

We explored romance then. It was great. We shared common ideologies and worked together to improve ourselves. I liked cheering for her marathons and sharing our daily rituals. After we came back from <country1> in May 2023, I proposed concrete steps on how to move forward together. She was quite enthusiastic about the idea!

I proposed flying to <city1> every couple weeks and volunteered to sit together and find her new jobs where she wasn't as constrained. All of these suggestions were waived away with "Yes! Let's do this, but tomorrow".  I proposed coming to <city1> and working together against the problem. I was repeatedly turned down, but just for that day. "Try again next week". 

After stringing me along for a couple weeks, I called this person up and she said she had been dating for multiple weeks. I wished her the best and ended things on a positive note. In an interesting twist, her new partner called me up the same day and harangued me for cheating on him with her. I assured him that today was the first time I heard of him.

We discussed timelines and found out that she had been engaging in physical acts all the while I was trying to forge a life together.

There was no intention to let me know, or to let me walk away so I could focus my energy productively. She let me propose solutions everyday, and led me along on a blind chase while she explored other avenues, carnally and otherwise. All of this can be verified with Mr. <partner2> . Upon finding that I had been enlightened, I was summarily blocked.

2025

Two years later in June 2025, she reached out to apologize saying "Karma comes around after all" after her then relationship with Mr <partner2> ended. She said she "wanted to make things right". I met her for one day on August 2 2025 and was given no response when I inquired about why the desire to reach out and make amends only arose after her previous attempt ended unsuccessfully.

Nevertheless, I stayed cordial. On august 10 2025,  she claimed that she didn't want to be scrutinized for her trustworthiness and that she deserved it unconditionally. Moved by such a rational argument, I restarted exploring paths together.

Throughout November, December and January, I requested us to collaborate on a solution. I suggested meeting in person and solving this. I searched for jobs on linkedin in <city1> for both of us and applied for positions in <city1>so that we could be close by. I talked with dozens of people and arranged a place to stay in <city1>. In contrast, I received a sum total of 0 suggestions or actions from her side. All of my proposals were shot down with one of two responses, for 90 days. The first was to think of yet another new solution. And the other one from this person - who cheated on somebody with me, then two-timed with somebody else, then met me for a total of 1 day after 2 years - was that we should get married immediately without meeting in person.

I made it clear that I had always been serious about us, both in 2023 and 2025. Us meeting each others' parents wasn't proof enough for her.

And I worked hard towards this goal. I wanted to go on runs with this person. Cheer for her as she completed her next marathon. I wanted to cook <dish1> together for her mom who had done the same for us when we went to <country1> . I wanted to share the same views when she went hiking with miss <friend1>. I wanted to give her hugs and a warm water pads for when she had cramps. I wanted to pet <dog1> with her and create new fragrances for <her company1> together. I wanted to hold her hands as we navigated this journey together. I wanted to see her smile and keep it turned upside up, and hold her when it was the correct time for it to be upside down.

All this while, I kept asking if I could fly down to <city1> so we could work on a solution together. The answer was always "no, we could do that after marriage". I'm sure you can infer what had been going on her side all this time. The road towards becoming a worthy partner is unending, and I hadn't perfected it back then. However, I believe I was honest, willing and caring. I don't understand the need to unapologetically deceive, breadcrumb and commit infidelity.

This person moved away the moment she no longer needed me. I am writing to you because there may come a day when she no longer has a need for you either, and you should be prepared for it.
