furious, terrified, and dont know what to do

okay, to start off i have struggled with depression in the past but i truly think im getting better now (yay me) but i have my reoccurring moments. my boyfriend on the other hand, is very depressed and im afraid he is suicidal based on what he tells me. im extremely worried about him. my mom wants nothing to do with the situation, his family kicked him out and hes got no communication with them, and now the friend he was living with is kicking him out, so long story short the love of my life has severe depression and anxiety and is going to be living on the street, he cant stay with me and isnt making enough $ for a place of his own yet. im hoping to move in with him asap and help pay for things but i also dont know how to talk to my mom who is going through a divorce and im afraid of leaving her alone. any advice?
