'You're crazy', 'can you hear yourself?', 'this is all in your head'

[Hatethesephrases]

AIBU to hate these phrases in a serious conversation? And if someone uses this line of argument on more than one occasion, why on earth would they want to have much to do with such a 'crazy' person, and basically, could you fuck off with that? Someone I know has done this a few times to me. Once, very recently when I was trying to have a serious conversation with them about them being overly aggressive and now pretending nothing has happened or that I have misunderstood. This is not a romantic partner btw.

I obviously could be mentally unwell. Maybe i have become unwell and have completly made things up which I now believe are true (I think this is unlikely). Maybe I HAVE misunderstood. But if so, saying this^^ along with sniggering, side eye and smirking clearly isn't the way to address it and isn't good for either of us to have a close friendship? I'm sort of convinced, after discussing with a mutual, third party, that I shouldn't attempt to get deep with this person again, just keep things superficial.

Excuse vagueness. Trying not to be too outing.

It sounds like gaslighting really
They're trying to dismiss your opinion by calling you crazy rather than actually listening. Not a person you want to be close to if you ask me

Yes, gaslighting. It’s a friend saying this? Not a good one, I don’t think I could be friends with someone this rude to me. It’s a very serious thing to say, IMO, it sounds like an abusive partner talking.

Sounds like gaslighting.
Run.

That's what I think too @Shoxfordian. This most recent occasion was so frustrating. I was half thinking, christ am I acting like someone who has become disillusional? But looking back, I don't THINK I was. Annoyed actually that there was nobody else there.

Delusional*

If you don't mind, I won't be too specific about who it is. A member of my family. Not a parent, child or partner. I have posted about them before on here under my usual name and got support. The thing is, this person invites themselves to stay with us and loves my dc. Why would they want to spend time with me of they think I'm someone who is making things up about them? It is when I say something critical about them they do this. I feel as if they have no respect for me at all, unless I'm pandering to them.

Say no next time they invite themselves op

Sounds like my ex.
Sneery - as if anyone could be quite SO stupid.

It's something people say when they can't muster a cogent argument for their position. In other words, they are too thick or unsure of their argument that they have to resort to insults.

After this latest incident, I am going to have far less of a problem saying no, fuck off, next time they elect to descend on my home and family.
