Hi there,
Welcome back from your trip. Maybe I'm too much of an optimist, but what I see here is that people like to be with you and open up to you. That's a real asset in my opinion.
However, I agree that revealing intimate information, oversharing and/or emotionally dumping on you in the context of a casual relationship can be a red flag. I'll give you an example. My sibling was recently excited about a first date with someone who, on paper at least, seemed ideal. They had met at a club, and they had some friends and interests in common. But during the first date, she brought up the topic of prior abuse by an ex, volunteering the information, out of nowhere, using it to explain her reluctance to do certain normal activities.
When my sibling discussed the first date with me, we agreed that this was a giant red flag--oversharing, victim mindset, sympathy seeking--alongside a yellow flag (multiple food restrictions that she volunteered and discussed in detail). Though at first he was disappointed, he felt fortunate to avoid a minefield. Here's the kicker: he was expecting that the date would reach out to thank him, because he had arranged a lovely evening, and he had spent most of it listening attentively, with understanding and patience, to her various "issues." Well, she never even texted to say thanks. That absolutely put the nail in the coffin.
I guess what I'm saying is, in a way, you might have the advantage of recognizing toxic behaviors, because you've navigated them for so long. I think I've learned that, too, to some extent. I don't think you should beat yourself up for encountering these types of behaviors from time to time. Actually, I think these behaviors are almost ubiquitous. In a group, there always seems to be that "difficult" person, who is entitled, demanding, self-centered, a drama queen, finding offense everywhere, manipulative, etc. I think you're lucky to know it when you see it. One place I've seen it frequently is in job interviews. For example, the candidates who are highly critical of their prior workplaces, colleagues and former bosses. The ones who never seem to stay anywhere for long, and can hardly come up with anything positive to say about their prior experiences. These are also the candidates who don't extend the courtesy of sending a thank-you. I guess I'm saying, I think it's important to be able to read the radar screen when it comes to general attitude.
All the best to you.



. The two of you weren't best friends for years, you were aquaintances in the park, and she says this.
