Quick question about romance. Am I with Gil?

I don't actually know. I did see this youtube video and it claims Cora broke up with Scott about Gil. If this is the same scene you got, my guess is probably. Check your codex and see if what it says regarding Gil and Cora's relationship with you. Maybe it will shed some light there.

Well, keep flirting with everyone and see where you end up. I'm told the prima guide says that three flirts is what it takes to start a romance. You only did it twice with Gil. And you haven't committed to him either so I don't think you're locked out of anything just yet. When you talk to other characters, do you have the "I'm interested in you" option showing up on the convo wheel? If that's available, I would consider that a good sign. You can always click on it and see if they're agreeable to starting something with you and then reload.

Checked the codex, it doesn't say anything about my Ryder being in a romantic relationship with Gil, just that they're friendly, and that Cora enjoys flirting with Ryder.

Maybe there's hope. What's making me worry even more is that I did flirt with Gil a third time when we were playing poker just to see how it'd go but then I loaded the game to make a different choice and I didn't flirt with him again. I knew I didn't wanna flirt with anyone but Cora and Reyes (and maybe Peebee) more than thrice. Now I'm afraid there could have been some confusion with the save files? Not on my part, but I've read some bugs of the sort have happened.

Well, I'll try to do her loyalty mission and see if I can flirt with her again. And no, I don't even have the option of telling people I'm interested in them yet. I'm earlier on the game, that's one of the reasons why that scene with Cora "calling me out" was so odd to me (although if that was just her way of warning me she's onto me and I still get the chance to prove I don't want anything with him, but with her, that'd be awesome).
