Please have a look at this

Hi, experts. I'm in need of your expertise. I have written this. Please have a look.

I know you say you're fine, but I don't know if I can trust that. I know you wouldn't want to talk about it, but actually that's what has me worried, because I feel like you've been pulling away. You don't talk to anyone. You just sit at home doing nothing. Which is very disturbing because you've always been this happy outgoing guy. So don't tell me that nothing's wrong, OK?

Is wouldn't OK here?

Also, is because I feel like you've been pulling away correct or is it missing something?

Thanks a lot in advance.
