Was this my fault? Am I too dumb? Please help me!

I mean saying "I wont comply" is a bit rude for person you care about about something minor as a picture..
I think its a bit more the way you say it,
If you go on being calm and polite in stating you dont feel comfortable about it and also ask if thats okay with her, I dont think it should create problem.. IF what you said isnt just rephrased in the post.
Of course nothing wrong in what you said, I just think the way you present it is what can offend others. It shouldnt offend anyone of course - but we all are different and require different approaches.

After scanning through this just adding my 2 cents:

1. Nothing wrong with stating your opinion honestly, but kindly and sticking to it - ever.
2. If I were in your place I would've tried to circumvent that with: "You can take a picture of us together, but as I told you right away, I don't take selfies, sorry." (as long as you're fine with that, of course)
3. Don't get worked up about stuff like that -> there's plenty of fish in the sea... ;)

Where are some people who like live by own dreams. Perhaps this applies to her.
But, where something else too. Where are some people who don't like "digital"/"internet" relationships without it in real life. Therefore, she could perceive the reluctance to take selfies as a rejection of the transition to a relationship in real life.
Thank you for GA

You dodged a bullet indeed xD

If you met her alredy, it's not that she's afraid of being catfished,
Well, as a woman, I'd say you dogded a bullet. A very big one. She wasn't into you in the first place if she needed that little to end everything. Also, I'm always a little bit suspicious when people claim they are in a relationship after a very short time ( but that's just me being an overthinker, I guess.)

nothing wrong with you, probably she has some kind of psychological issue Idk, anyways I won't bother with her especially if she's not so familiar with you, maybe the both of you had been chatting just for some weeks so who cares.. let her go, you did nothing wrong

I assume you only met her on the internet? Otherwise it would make little sense that she deleted you.
I seem to be part of the minority that's actually siding with the girl in this scenario. The internet is full of weird people and more than once I found that the person behind a name isn't what she was claiming. Sometimes not even the same gender!

And while a picture doesn't proof much, straightaway denying it could be considered as a warning sign from some.
Especially when you've been around the internet and/or looking for someone for some time, you don't have the time/patience for games and want to know what you are dealing with.

No, I won't comply, I don't feel good doing that

She is weird, but your choice of words was awful. It might have caused a much worse impression than you intended.

That this person would have zero qualms about making another person feel bad by deleting them -- I hesitate to think the person's outlook on other people's feelings too (like your friends' feelings).

I'm the same way. If someone can't get to know you without knowing what you look like, they probably aren't the type of person you want to know.

Time for relationship advise 101 with Blep. Fuck her you can find someone better.

I don't think you're weird at all. Just the way you worded it might have come off as rude ya know.

Just ask yourself if you want to be with someone who has no notion of privacy. Personally my answer would be "hell no".

Edit: btw, I agree with @Joys about your choice of words. Did you really write/say "No, I won't comply, I don't feel good doing that" or is that an edited version for us? I mean, it feels like you're talking to a police officer who's trying to enter your house without a warrant here ^^ I don't know how I would have phrased it, but I'm sure "comply" wouldn't have been in my sentence. Maybe something like "You know I never have my picture taken ;)".

It's like when Wendy on Southpark flipped sh*t when Stan hadn't added her on Facebook.

well i guess that is what we call 'damaged goods'. better pass that one.

though i have to admit, if i was into that creepy dating stuff i'd like to see a picture of the person i'm talking to as well. nobody likes nasty surprises. but that's no reason to overreact.

If she was truly interested in a relationship, she would have:

A) accepted your answer that you don't take selfies, and that would have been that.
OR
B) asked you some questions to try to understand more about why you might feel that way about selfies.

The fact that she chose C) never speak to you again tells me that she was not interested in any sort of meaningful relationship.

"No, I won't comply,"? sounds a little rude to me. had you met online only? so she doesn't know what you look like?
if a person didn't want to send a picture after meeting online, it would be a red flag to me.

you talked to a girl!

You did all right, she is weird. Why do you even doubt about it?

On the one hand, if you had sent the selfie, that probably would have shown her you trusted her enough/you'd be willing to step over your own boundaries for her.
On the other hand, it looks like she completely overreacted. I'd take that as a sign that things would not work out in the long term anyway.

I wonder what would have happened if you told her that in a better way. Your choice of words could have easily came off as rude, cold and as if you're trying to brush her off.
Since she already saw and met you, her asking you for a selfie could have been her way of indirectly telling you that she likes you. Then you brushed her off with "No, I won't comply".
She still kinda overreacted though.
