My apologies for this being so teenage.
I've been on a couple of dates with a man I really like. I asked him if he was free for a drink yesterday, which he wasn't. Fair enough. So I text back saying 'Okay. Let me know if you do fancy a drink one day x', and the reply was 'Of course x'.
Is he saying of course he'll let me know if he does decide he fancies it, or of course he does fancy it? I don't want to make a fool of myself by beating a dead horse, but I've been single for years and really like him.
