Hey, I’m sure you didn’t cause him to break down. Maybe he’s just feeling so on edge anything would make him tip over, you know?
It doesn’t mean he doesn’t love you. You can’t know what he is feeling, right? Just assume he needs some space, that’s all. Do your best not to make a big deal out of it when you see him. If he knows you can be cool and calm, things will go better.
Hang in there
