This deeply resonated and perhaps what tugged my heart the most is the fact that there is no resentment tied to it (joyful nostalgia) - although I wish you hadn't had to discover it that way - but again I get why he might have not found it in him to break it to you that he met someone else
I especially loved how you described holding hands - in this age where I feel such sweetness & innocence is rare, it took me down memory lane 💚
