What movie did I see??? Help

Ok I’m trying to remember a movie where they finally hook up and it goes something like this

Him: last night was Her: a mistake I know Him: that’s not what I was going to say

And then he’s basically like “I know we’re endgame so I’ll just bide my time until you see it too”

I can see the scene so vividly in my mind but can’t place the movie for the life of me
