My gf(21F) reply to my(26M) message with a simple "ok"?

Yesterday I was on a date with her and she took a picture of me and uploaded it on IG. But less than 5 minutes she deleted. When I asked her why, she told me it was nothing bad, she deleted it from IG. That was her response. It made me mad but because we were drinking I didn't keep pushing it.

So an hour ago, I texted her this:

Hey love, I wanted to tell you something, it's nothing bad but I need you to know.

It bothered me a little that you uploaded a photo with me, and then suddenly deleted it, and when I asked why you, told me that you deleted it just because, for no bad reason at all

It bothered me because I like you a lot, and when you take a photo with me and upload it to your social media, it makes me smile and makes me happy, but that you suddenly delete it and don't explain to me why, it makes me a little sad. And it's not the first time you've done it.

Because if you deleted it and you don't tell me why and you quickly change the subject, it makes me think as if you were hiding something.

Because if someone uploads a photo with someone and they quickly delete it and give no explanation, the person can get upset and that can create insecurity.

Anyways, I just want you to think about it the next time we take photos and you want to upload it. Or ask me if you can upload it. Don't do that to me again pls

And then her only response was an "ok"

I don't even know how to reply to that.
