My boyfriend doesn't know how to communicate

So, my boyfriend is 18. I will not say my exact age to avoid the same old annoying age gap hate <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> has, but I am over 40. He is also Vietnamese and I am white. He is still being scheduled to work by his manager (He works at Burger King) and had a drink thrown at him and racist insults like ch*nk & bat murderer. He was sent home early and has just been pretty closed off. He won't talk about it and will just cry and snap at me for asking if he's okay. I told him I'll give you time but please don't risk your safety and mental wellbeing for a burger king, if you need to quit then quit. I just want him to know I'm here for him but I'm tired of him not talking to me about how he feels. I'm his fiancee and I WANT to be involved. Does anyone else experience this? Because I've noticed men have a hard time healthily communicating.
