Exactly because any other day he would give me a heads up if he wasn't coming straight home. Now all of a sudden I don't hear from him.

I wouldn't call .....he's most likely doing it on purpose assuming you'll be calling .... If it gets too late (for your liking) then yes call him but for now I would wait it out ...especially since he called you clingy

He's probably with a friend

Yes we live together.

Do u guys live together? Yes I would call!
