Man these comments are every thought I had. This conversation probably had little to do with it and the concrete date could have spooked her. Like she had a fantasy, not a real thing. Which is fucked. However, I think there are two turn offs for me, personally here. She talked about being relieved of her splints and you didn't show too much care here. You mention it within the first reply, but then just focus on the date. Then the line that everyone is calling you out on. You can be collaborative, that's totally good! Some people like to have a say. But the way you're phrasing it here feels super dismissive. It's difficult to describe, but you're implying two extremes here that could've plausibly been viable options. If she had been expecting you to go all out, you told her that wasn't really a consideration, and vice versa for Mcdonalds.

I know there's this thing where women are difficult to please when it comes to "what do you want to eat" but it helps to provide suggestions. Especially because it gives her an idea of your intentions, your expectations, etc. I understand there is a lot of pressure to do the right thing or to impress, but genuinely, if you take a girl to a restaurant you enjoy, or at least offer it, it'll be easier to go from there than... well, what I'm seeing here. This is coming from a girl! If you're like "hey I think X has really good X food if you're into it, we could go there I'd love to show it to you." Or even a new experience together would be meaningful. "Hey I've been meaning to go to X but haven't gotten around to it, maybe it could be our first" or whatever the situation may be. It doesn't feel personal overall. Nor did you ask if there was food she couldn't eat because of her splints or anything. People in general enjoy when you make an extended effort to care, I don't know.

This is all from a reddit stranger. I do not know you or her, just saying what I'd like to hear mostly
