The arbiter of what someone's intentions were is that person. Who else would know what they are thinking inside their own head? People do not owe you an apology because you misinterpret their intentions. In fact, if you accuse someone of bad intentions where there were none, basic decency would suggest that the accuser is the one who owes an apology. Of course, it's possible that someone lies about what their intentions are, in which case, sure demand an apology all you want. But it's not likely to be fruitful to continue interacting with someone who's deliberately trolling you.
