Clingy can mean many things to be quite frank, clingy can be touchy and it can also mean being too dependent on your date. Don’t expect him to reply instantly and everytime before he picks you up, unless he’s commuting, chances are he’s driving. You also don’t need to call him up as soon as he drops you off. Let yourself breathe first. Feel the room and the moment, you’ll know best when to thank him for the wonderful day. Don’t get overly excited, he didn’t ask you to move in, he asked you out.
