It doesn't matter to me if you think I'm taking balderdash because I have a red flag there myself, and I walk away from people who speak to me like you have. That's how boundaries work. I don't have to care about what you think of me, I don't have to control you or tell you to stop saying the things you say. We don't have to have any tricky discussions, and you don't have to understand where I'm coming from. I distance myself from you because you are saying unpleasant things about me, I've checked that I respect my own behaviour/words (and I do, I stand by what I've said) and so, all I can do is stay away from any further engagement with you.
I wouldn't have replied ordinarily as I don't need the last word in a debate. However you appear to have labelled me as abusive and I won't take that without acknowledging it. Is that what you meant? NIce bit of gaslighting there.
You quoted one part of your first post and left out the rest. This is what it said:
Red flags aren't his behaviours. They're your feelings. If you get the red flag feeling, it's a red flag for you. End of story.
You might feel a red flag feeling if your date eats a Mars bar, and your abuser when you were a kid used to eat Mars bars just before abusing you. It doesn't mean that eating Mars bars is a 'red flag', it means that for you, eating Mars bars is not a viable behaviour in a partner. You are incompatible with Mars bar eaters.
If you feel the red flag feeling, it's a red flag. It doesn't have to make sense. If you're with a long term partner who's done a hell of a lot right, you might have a conversation about it, and he'll hopefully say he didn't realise it was a trigger for you, and he won't let you see him eat a Mars bar again.
Red flag feeling for a first date? Don't go.
Hopefully that shows why I questioned your definition of red flags. You said that red flags aren't his behaviours when they 100% are. That is the very definition of a red flag. It was totally unnecessary too when the OLD man had blatant red flags flying anyway. No need for a redefined definition.
Anyway I'm leaving this now. I hope op has taken the posts on here onboard and blocks this man.
