advice for healing from emotional abuse (in friendships) ?

does anyone have any advice on how to heal from being emotionally abused in a friendship. we recently moved in together and as soon as we moved in he started treating me like he doesn’t know who I am and stonewalling me. I don’t mean like he just doesn’t wanna spend time with me I mean he completely ignores me and won’t even acknowledge when I’m in a room and avoids eye contact yet he treats all of our housemates with respect and acts normal with them . and yes I already have communicated to him what is wrong. i’ve done nothing but be very good friend to him and I’m the one who even found him this place to live that he could afford in the first place. it’s been hard because out of our mutual friends no one believes me because it is so subtle and he is putting on a good face to everyone else and only being rude to me behind closed doors. it’s been really hard since we live together it’s not like I can just get away does anyone have any advice on healing from this because i’m so tired of being sad&just wanna move on and be happy. I moved to a complete new city so that I can start fresh and as soon as we moved this is what I had to deal with it has literally been Traumatic for me please give me any advice you think could help. another thing that has been Trumatic is all our friends not believing me because I have done nothing to prove myself to be on trustworthy when he has done multiple things just in the past couple weeks and made multiple of our friends cry by his actions.
