am i in the wrong?

my bf literally said this to me today and it’s been a trend. he won’t let me leave but i make him feel like this apparently. last weekend he said something like he needs to leave me alone. i have to show him everything i do basically or he doesn’t believe it, i’ve never cheated. i caught him calling a girl his baby mama last weekend as well. when we argue he says if i leave the house we’re breaking up. he’ll ignore me for hours while we’re in the same house. he says i talk too much, complain too much etc. i’m so drained. i want to leave but don’t know how and i’m scared of adjusting all over again. please tel me if i’m doing something wrong…
