Should he have said more?

My boyfriend called me around 8pm and we had a good talk i wanted to say how i was feeling but he was around his roommates so I didn't want to give him a hard time. I know its bad to say in text but I told him how I'm suicidal again , and he just picked the conversation up completely skipping that part, he has a lot on his plate and its almost 12am , I should have saved this for earlier I just felt so close to the edge, and I was gonna call a hotline but he said I could talk to him whenever. He sent me a funny video And then i said goodnight baby and he said night. I dont know i know im in the wrong for sending it in text and so late at night but I wish he'd said "it'll be alright, " I hate being a burden but I have bipolar disorder and I can't help it sometimes I break down I held off telling him for months and i blabbed it in a text.
