I guess he could have been talking to someone before you though and made plans with them Sunday..or he was speaking to someone at the same time as you and met up with them a bit before.
Just ask him. Honestly we spend all this time incorrectly guessing and the only way you’ll know is if you ask! Saves time and then you can move on. Thank U NEXT and all that. Either that or just delete and move on. If it’s unacceptable to you that he hasn’t contacted you by now then there’s no future anyway! Go on honey, take a chance - oops another American comedy reference! Go USA
