Im sorry for that, it really sucks when a discussion ends in misunderstanding! 
And yeah, communication in english not as a mother language is even more difficult.
I like your curiosity and your engagement here 💪🏼 and maybe sometimes we need to better sense if it’s worth it to discuss something. And this situation is probably not that bad, you got this! :) 

 I come across this so often due to communication via text. Tone of voice, facial and other physical expressions, etc are taken out of the equation and can lead to misunderstanding when you don’t have those subtle visual and audible cues to sense the full context and meaning of what someone is saying. It’s why emojis and memes can help with expression 🙂
