Saturday came and didn’t receive any message so I had it set in my mind he’s playing games and blocked him to not get my hopes up on receiving a text. That Monday, he sees me at work and asks why I didn’t text/call him then later ask if I wanna go get something to eat after work. I said no b/c he doesn’t get off until 10:30pm and I know where that leads and said we could go tomorrow. I texted him to confirm, he said yeah and asked what time. I brought my clothes to work to change afterwards expecting to be going on a date after a meeting we had but he texted back like an hour before the meeting saying let’s go later. I said never mind and he said if I think he’s playing games, f it then. I explained his lack of communication is annoying... of course no response. Buuuut, we're all in the meeting together (me, him, and the chick I suspected he was messing with) and eventually he tries staring at me and I make it obvious I’m pissed off and eventually he starts texting the chick, laughing and talking to her across the room (while he’s sitting next to me) , passes one of her friends his jacket which she gets eventually then when we leave, he walks with them.
Obviously this is immature but I really want to hear others opinions about this behavior
