i triggered my boyfriends suicidal thoughts i feel horrible

Hes really suicidal, we were texting and i said that id kms if i fail or get atleast myself admitted to a hospital.
i dont know why i would ever say that, its so fucked up already. i feel so horrible. i apologized allot but hes not responding im really really worried.
i think ive fucked it all up- he was doing better.
i was suicidal around may it was already so weird for me to say something like that.
he said that he already gets weird thoughts and i made it worse for him, can i help him somehow??? im so so worried he isnt responding
