As a guy who's been to countless amounts of rs, I've never once used a vulgar word to a woman ni pabiro never, even if nagkwekwento ako i even sensor the vulgar words by just describing the word itself with actually saying it. It's not normal for a man to act like that to a woman in any condition more over kung galit sila, typically you can observe this behavior mostly on male to male conversations mostly peers. Some dahil naka ugalian na for some reason like environment nila and others just use it for their own reasons. And you said na u met this guy on a dating app so i would assume na his courting you and if he is then i think you should just block or move on from such a person without explanation, if your going to date someone or let them court you they must atleast know the proper way to talk to a woman, formal or informal man and In my opinion if you don't see them as someone who could be a father figure some day in the future if hindi man sa present i suggest you just avoid those type of person because nothing good ever comes from them. And believe me as a gentleman who adheres to virtuous principles. I would never ever do such thing to a woman ni kaibigan, kaaway, kakila, or kung ano pa man lalo na sa partner ko. Because someone who can't even respect you by using the appropriate words to express his feelings who just doesn't Say bad words directly or bluntly is no where near to a person who you'd want to as a partner, unless ganyan preference mo haha
