should I tell my bf's mom and sister about his suicidal thoughts?

my bf is going through depression and says he doesnt want to wake up. he's made a mess of our relationship because of his depression causing him to disrespect me. he has tried to commit suicide 10 or so years ago. his depression is bad and I dont know if I should tell him mom and sister. I have only told some friends, but they can only talk and be there for him so much. my bf has almost completely shut me out by either asking for space and ghosting OR not saying a word on a phone call or in person.
