What to write in the elephant in the room letter

Hi, I’m thinking of breaking no contact tomorrow on the day after tomorrow with a text message(as she has erased my number and we no longer have friends in common to give her the letter)

I’m thinking of writting her before her professional nurse exam, but not on the same day as that day would be my birthday, don’t want to look needy or like I’m locking her into contact with me because it is my birthday.

I do want to wish her well, inform her that I’m doing better and accept why she has broken up with me(I really can see why), although rumor that got to me was that she is angry because she thinks I cheated on her because of some picture?? She didnt bring up any of that up when she broke up with me but could explain why she was so cold, and I never have cheated on a gf. I have had casual sex weeks after a break up, but never during the relationship.

Any way, I don’t want to mention that I’m doing better quitting the pot(I am, but it’s something I had told her many time) and it might remind her of the issues she disliked most.

Something along:(Also, this would be in spanish in the real text)

“Hello, HER NAME

I hope you are doing very well. I just wanted you to know that I agree with the break up as I have had time to see what was wrong with me, since before the break up I know I Was not acting my best at all.(When she broke up, I did not beg, I did show how much it hurt but we didnt hugm kiss, shake hands or anything, just turn around into the car and she went inside her house, but before we were arguing constantly and I was not eating or sleeping since before the actual break up.) while I am struggling a bit to be better at communication, the therapy is helping a lot with that and I can see positive results at work and in my life because of it! Hope you’re healing as well and doing good.

Also, I wish you luck on your professional exam in a few days!
It would be great to tell you more, and to hear how the exam went, but in a little more time as I feel that we both need more time and space”

I didn’t want to make something too long or too mushy, as I was very needy and overly affectionate with her and she would be getting colder and colder, attributing that to her life experiences and her not being the same as when we started the relationship(at the beggining everything was so warm with her and during the relationship I began missing that more and more, I just kept blaming myself as I didn’t belive her, I atributte it to me not fulfilling her or something around the area, hey, it might be both, but I’m focused on my end usually). So, I would just like to send her a text that would at least put us into communicating again without any issues. As I’m still confused if I really want her back or want to try talking with her first and testing it out with an actual change, as I was SUPER negative before the break up, after it, I have been trying to keep my head out of water and doing things differently
