Playtime is over. He knows his strength and enjoys hurting and humiliating you, that's why he isn't sorry because doesn't care.. Its time for you to stop caring about him and saving up for a place for you and kitty.
No more flirting
No more ordering food for him
No more watching tv with him
No nothing...fuck this guy.
Just do the bare minimum to avoid abuse and buy time to save up and then ghost his ass.
