[X] "I… I don't know if I'm ready for a romantic relationship yet." You're gonna settle things in your life before you attempt romance, once that's done… who knows? (This is the option to deny romance, at least for now)
[X] "Maybe we should take it slow and see what happens?" You'll take things slow, let whatever spark that's growing between you two develop on its own. (This is the option to let things remain as they are now)
