If you can, like her message and just wait a couple days. reengage her with a “hola linda” or a famous ryan gosling meme and try to lock in plans for that week. you don’t want to seem needy, as in when your plans fall through you need to immediately make other ones. give her a little bit of space. maybe even reference the cookout when you’re confirming and use humor to make sure she doesn’t flake ie: “so no unplanned family cookouts getting in the way of our romantic date?” etc.

“Sounds like it was official”
