Ever have to fight the urge to reply to a” how are you?” text from the ex?

I just keep staring at the words on the screen and watch my thumbs hovering over the keyboard, hoping that the words I feel in my heart just jump out onto the screen. I feel like if i reply with pure honesty the selfish feeling of ”well maybe they are feel as miserable I can find some odd comfort in that”.

What do I do follow my heart of what’s the harm of a text of ”healing that’s how I am doing I am healing?” or just ignore the text like it never existed?
