She's highly controlling,
The conversation with jack on the saying he would go is the most recent example.
She told him in no uncertain terms he should not have said it, that it impacted her negatively. She never at any point said to him how do you feel, would you have went, let's talk about it, his feelings were totally irrelevant to her.
She then got into bed with him and actually asked him if he was in there "for the right reasons" insinuating if he didn't want to specifically be with her, then he must be in it for the wrong reason.
I do get when she senses it's going wrong that's when she becomes controlling, telling them what they can and can't do and say, and constantly being "pissed off".
But we shouldn't be rewarding bad behaviour. Kids watching this will think it's ok for your partner to tell you how to behave and what to say if she goes further in the show, it's not ok. Not by a long way. People need to treat each other with respect in relationships and when they go wrong, know they should try to resolve it mutually or end it. Not that you should force the person you're with to behave the way you want and stay with you.
