Perhaps. But you realize it now, and you also have the opportunity to take things in a different direction if you want.
Communication is important. Admitting when you did something that you think is wrong is good, we all make mistakes. Tell her that you're sorry and why, and let it be. Either she will forgive you and you guys can move forward if it works, or she won't want anything to do with you, and both are fine. Emotions are complicated.
If you want to try roasting, rub with just enough olive, avocado, or corn oil (my preferences in order), and sprinkle with salt, pepper, garlic (powder works just fine but you can crush some fresh or use paste), and onion powder, and throw it on a sheet pan with parchment paper or foil from 375-425 (anywhere is fine - I prefer a bit higher because I like it to be crisp and a bit med rare in the middle, but if you prefer it more well then set it lower). You can brighten it up when it comes out with a bit of lemon if you like, but that kind of depends on the rest of your salad.
Tastes great with a balsamic, Caesar, or ranch style dressing. I like to use a smoked paprika vinaigrette that's a bit sweet.
After you pull it you can let it cool down to throw on your salad, or just send it hot!
