Podcast and the mysterious blue to green text

What a relief - i THINK I found another mystery why my text to my boyfriend suddenly turns into green box….he’s listening to his podcast shows!!!

i feel bad for the stress I added to our time together accusing him of blocking me for his privacy. Then he’d look at me as if I lost it…why would I block you??? He responded - I showed him the green text and repeated with google findings of being blocked. Then, because the podcast findings was not in the mix yet - we matched my msgs to what he received and found only some of my green text were received on his end - not all of them.

Till one day I couldn’t wait to share a pic with him and sent my text while he was in the other room on podcast. I saw my text turned green. When he came out of the room I asked if he saw the msg I sent - he said……wait for it….no.
