I've posted a bit recently on how to reply to texts.
If you took away your fear, your needs, your anger, your pain, and all that was left was just a moment of peace, content, closeness with God, appreciation for your new life...what would be left? This is your higher self. This is the voice you need to speak from.
Personally I would reply. If you died tomorrow I wouldn't want to have left a legacy of not responding, acting coldly. But I wouldn't be all needy/clingy like "I love you forever". I would just call it how it is. Something like "It's all good. We had our fun along the way, and I know great things are in both our futures."
Then go and make that a reality
