<human>: Condense the text into a few key points

My best friend, Theo was just kicked out of his house for being gay. Theo has been out in the friend group for years, but he's never told his family because he was afraid of how his dad would react. One of his classmates from highschool did not know it was a secret, mentioned it to her mom, which got back to the Theo's dad. Long story short, his dad kicked him out, and he was only able to grab his phone and his wallet. 

He came over to my house, and he is currently staying here with me and my mom in one of the spare rooms. The trouble is, I don't know exactly how to help him! Theo's mom and sister are trying to convince his dad to let him come back to the house, but I don't know how safe his home would be for him? I don't know if I should encourage him to stay at our house until it's time for him to go back to college, or if I should stay out of it entirely. If he does come live with us for now, what needs to be done? I've already told him that he should get his important documents from his mom to do stuff like get his drivers permit and make sure his father is not able to access his bank account, but I am sure there is so much I am forgetting. 

My mom wants to stay out this situation entirely, and not get involved. My father was physically abusive to her and my older sister, and none of them like to talk about that time. I remember bits and pieces of how scared they where when I was younger, but I didn't experience it like they did. I don't think my mom wants to deny a safe home to someone who is in that situation, but she is also afraid of getting into a situation like this again, I am afraid of bringing up bad memories by asking her for advice, which is why I turned to reddit.
<bot>: What should I advise my friend who got kicked out to do, stay at my home or go back to his? If he stays with me, what do I need to do to help him stay on his feet and be safe?
