Ex quickly jumped into LDR rebound with her friend

My ex, someone I dearly love, recently left me after 2 years. She had good reason to, I was ultimately neglectful; i made her feel alone, unloved, unwanted, and I didnt show her I was listening to what she said. It hurt, and I accepted it without a fight.

It’s been just a few weeks, so I understand that its too soon to know anything for sure but…

She quickly started sexting with a close friend of hers. She just wanted to rebound and get her mind off of me. Turns out he was in love with her, and they are talking about dating. He’ll be flying down soon - pre established plans, and its not the first time that we’ve had friends fly in to visit - and he intends to start a serious relationship with her.

Im focusing on myself - will be doing that no matter what, I need to be a better version of myself - and… I hate this. I get that it was a rebound, I get that she had reason to leave me and she knows it. I get that its a LDR and I don’t know how she can handle that. And I hate that what was just a rebound turned into a potential relationship, especially because I still want to rebuild with her.

I will become a better version of myself no matter what, and I want to become a better person with her, show her that I can grow and show her I have been listening.

She still wants me as part of her life. She values my friendship and loves me as a friend, but I don’t want just a friendship with her. I wanted to take this to the end; to grow old and eventually die with her.

And I’m seriously questioning if I should even bother hoping to rebuild or if its time to give up and move on…
