This wasn't an unfair question, and it was something Natasha had considered herself. Maybe not from the same angle - she would have been a little startled to realize his concern was that one day, she might wake up and regret what she had given for him. And maybe she would have broached it a little sooner if it wasn't still so entirely heady to have him look at her that way, she still couldn't quite figure out how to get on top of it. A Clint Barton who looked at her like he wanted her and whose only hesitation in reaching was how she might feel about it.
"Obviously I care but," she echoed, and let it settle. She kept her fingers in the crook of his arm as she did, though. Because he was here, and because she was allowed to, because he would let her, because she wanted to. "It's not like it isn't... a salient point, Clint. Classic overthinker here, if I spend too long working out a problem, I'm pretty likely to tangle it up into several more knots than it had in the first place. I know that this is a stupid time and that the right play here is to sit back, and be friends for awhile, and see what happens."
Her fingers pressed a little further into the crook of his elbow, as though she was trying to prove to herself he was still real. No other way to do it but out with it: "And James is a factor too, for me. Bucky," she clarified. "Until I washed up here, I had no idea that he even remembered what we were to each other, that was something I thought I'd put to bed. I would be lying to you if I said that's another door I never took that I badly wanted a chance to take. So - yes, this makes it a hard and strange situation on a couple fronts, maybe it makes me a completely selfish monster, but..."
She had chosen this. That's what she was trying to remind herself: because it would be easier to stop talking, easier not to open up, lay it on the table, gesture to her underbelly and say here, right here, this is the place you want to take a shot. Of course it would be easier, but the person who had chosen easier had died on Vormir and when she'd woken up, she wanted to be someone who was done avoiding the truth just because it made her vulnerable. "But I also don't know how to look at you and not want you. You-you. You're funny, and you're kind - God, Clint, you're so kind, it's crushing. I know you're not perfect, I'm not - throwing you onto some kind of pedestal. I'm saying I know you. I know the good things, and I know the bad things, and I've still never known how to stop wanting you. You're my best friend. My world's a shitty place without you even when I sometimes thought not being able to touch you was something a person could physically die from, it's disgusting to want like that."
