Write your final blessings to your ex-girlfriend

Final blessings, you two have separated, you want to write a paragraph to her.

I am very happy to meet you. It is also my greatest luck to know you. Thank you for the good time with you. When I am with you, I also feel a lot of joy and happiness. I know that sometimes I may not take your feelings into consideration and make you sad. I also want to say sorry to you here. It's a pity that I couldn't be with you in the end and didn't go on. I will not be involved in your future life. I just hope that you can find someone who loves you more and be happy. Finally, I hope you can live a happy, healthy and happy life forever.
