Im furious! Boyfriend left baby to nap in crip with blanket!

Ladies, i am furious! My boyfriend left my 2 month old son in the crib with a thick blanket while he fell asleep in the bed. Im so angry and ive already talked to him but hes quiet and not responding really. Even after me explaining how he could have suffocated and died in there. Now as im writing this im in tears emotional because i could have lost my baby boy right then and there under the surveillance of his own father. I don’t know what to say or do. I dont want to keep tearing down my boyfriend about this but this is not okay. He just left to go shower without saying a word. I dont know what to think. I get it mistakes happen but this is not okay to me. Im not visibly mad but i am on the inside... as im feeding my baby boy right now. 😡😭(fyi so you guys get a greater picture. he is a great father. He is loving caring and kind. He says he dozed off. Hes never done anything like this that would make me question him)

Despite what he said im still mad about this. Very angry😔 i feel like i cant trust him to take care of our baby right now.
