Typically when someone reacts poorly to another rejecting their ‘sexual’ advances, it is because they are used to getting their way, have a fragile sense of self, or use bullying to get their way. For some reason, some guys have it in their mental dating handbook, under the chapter How to Woo the One Who Rejected You, a strategy of using slut-shaming and threats. WHY? If you, as you say, politely rejected him — AFTER he clearly ghosted you following a few meh dates….WHY does he feel the need to stoop to this level? Imagine what his mother or grandmother would think if they knew what types of things he said to a woman who rejected him. It is my assumption that if he is reaching out after this long, and the previous dates weren’t something to write home about, he’s likely hoping you’d be up for something else. Again, I’m just speculating. Either way, some people need to learn the art of taking a “no” well. You have every right to decline, and also NOT give a reason. Why can’t (some) men (the ones who make the rest of them look bad) see and accept that?
