I Need to Rant

My boyfriend came over today and I could tell he was agitated so I asked him what’s up, how was work? And he’s like “really annoying. I don’t want to talk about it” and I asked “why? What happened?” And he’s like “I said I don’t want to talk about it. And his eyes were literally watering. So he wipes the tears away from his eyes and I asked him a couple more times to tell me, then I just gave up.
So we went out to eat, then on the drive home I decided to ask him again, and he still didn’t want to talk about it, so I said “if I was upset you would totally keep pestering me until I told you what was up” and he said “no I wouldn’t. I would realize that talking about it upset you and I would respect that. You’re making me mad even Still talking about this”
and then I just gave up. I’m so confused WHY not just communicate with me, makes me think I’m a bad girlfriend, like he’s randomly afraid to talk to me about something. Idk. I’m probably being a “crazy girl” and over thinking this
