My ex (g26) broke up with me (m28) after a year together on and off. She broke things off every time and recently broke up and pleaded for me back 3 weeks ago. I agreed even though I knew I was setting myself up for failure. After things seemed OK she came over before she went to work and broke things off. Things felt so rushed and sudden after just accepting her back. We texted briefly until the next day.

Things ended on a decent note but a week later I still had so much to say. I wrote a letter that apologized for my faults in the relationship, why I felt so strongly about things and my frustrations that I hadn't been able to fix things and communicate. Specifically when we were together she had tried to emphasize that she would never be unfaithful, since she had been hanging with a good male friend a lot. I never was worried about that but I expressed that it hurt that I no longer made her happy the way that others did. I left the note expressing my hurt about losing her but wishing her well on her journey to peace and happiness.

I dont regret what I said because I meant everything but God I regret actually leaving the note on her porch. I know I should've just burned it and moved on but I can't change it. I feel so guilty and all I want to do is text her to apologize for leaving it and that I'll leave her alone but that feels even more intrusive than what I've already done. I don't plan on texting or contacting her but I feel so awful and low for having done it. How can I move on?
