I sighed... he got triggered?

my boyfriend get triggered when i sigh or my face gets serious... i can get that for millions of my own reasons and he always triggers and starts:"whats wrong with you? whats going on now? what?"
Im like:" Im fine...
He is like:"i see you are not..."
Its like im Not allowed to be sad or thoughtfull or maybe even unhappy about something while being with him.
He avoids any medium serious talk too, gets annoyed and angry
