How would you respond to "your so beautiful"?

[AmanoYin]

If someone compliments you, you got a few options.
If you're bashful say, "thanks for the compliment"

But don't do that forever... you have to grow

You could return with a equal or better compliment. This should be bare minimum.

Make sure all your compliments are honest, find something.

Maybe 2-3 compliments if you're good with words and reading the mood, followed by a joke that changes the subject.

Since it's text you can drop a non-basic smiley face.

Thank you for your kind compliment, I wholeheartedly appreciate it!

[I_make_me_anxious]

I’d say thanks and try to respectfully ghost them...(I get a lot of 30+ year olds trying get with me)

[I-am-a-nobody]

Thank you is appropriate.
"You're making me blush" if you're interested, is good, too.

consider a compliment as something someone gives to you. what do you say when someone gives something to you? thanks :) so that's totally fine.

[crmoore]

I think thank you is fine. If you don't want to say that, you can say something like "I appreciate the kind words," or a mixture of both.

[COMMODOREII]

I usually say, "i know". And walk away.

Give them one of these

If someone told me that I’ll be like “ Damn I’m just beautiful and not handsome 😫”

[magiusX26]

thank you is not concieted. especially if you add some follow up banter

[Annoyums]

Therefore I have value? (Spiderman Quote) 😂

[BenimKralligim]

Fuckoff is an option too.

[coffeewithcream]

"I am, aren't I?" :)

[Iron_Man]

Just say thank you

[In_Trance]

I'd say "you're"
