Bf keeps failing to pay rent

My bf moved into this one bedroom pretty expensive.. he has trouble paying rent every month .. this month. He’s $600 short . He just called me to ask for money .. or he’s going to be evicted tomorrow .. idk what to do I’ve gave him $300 last month I believe he pays me back but it’s the principle . Would y’all let him be evicted and homeless ? He’s been homeless before in our relationship..
