I still deeply care about you and hope that somehow you accept my apology. I hope we can talk again, but please feel no need to respond to this.

Otherwise, thank you for the past 3 months. You made me so so happy and I looked forward to every text and every time we hung out. Every embrace filled my heart with love in a way you’ll never know. You and XXX are genuinely both amazing people and I wish nothing but the best for the both of you. Her words to me that night were very thoughtful, you have an amazing friend.

All of this needs to go. Leaving this in makes it very apparent that you are apologizing only in the hope that she will get back with you.
