This is my first serious relationship, so i'm newbie go easy. Do you just send msg like "i'll be there tomorrow night" or few days before "i'll come over on saturday, prepare wine" etc.

what if she is busy with friends, do you say "ok i'll be there on sunday"(like day after) or ill come tomorrow.

the thing is i am seeing her for 3 months now, and i have no issues setting up the dates, i want to know what do you prefer, tell few days before, or last day or even same day "ill come over tonight", based on success of her not being busy? i want to learn diversity, so i'm not predictable.
