At this point I really feel like she has been bullying him this entire time.
Maybe the relationship is different behind closed doors, but I really doubt it that these two have any meaningful conversations or even normal arguments, she's too controlling and he is too vanilla to even react to her madness.
All I know is that she really needs help.
And also she needs to work on her vocabulary. everything is either stunning or brilliant. English is not my first nor my second language and even I know that.
